[ovirt-users] Deleting old export backups in oVirt

[Wesley Stewart]

I am using a script to make weekly backups of my VMs, but I really dont
need more than 1-2 weeks per VM.  I pulled open my NFS share where the
export domain points to, but all the VM's have a long guid and I cannot see
which folder corresponds to which backup.

For example, when I click "Import" and then "load" one of the backup VMs
listed is:
Ubuntu_Server_BACKUP_20170731_012832

All I see are folders that look like:
"f42fd734-e5e6-964e-87D1-8dbc554f0e19"

Going into the folder there is a "META" file, which I can open, but there
is no reference to the actual VM name.  Is there an easy way to tell which
folder goes to which VM?

Re: [ovirt-users] ovirt 4.1 : Can't install guest tools for Zentyal 5.0 (based on ubuntu 16.04 xenial)

[Wesley Stewart]

Just wanted to add my input.  I just recently noticed the same thing.
Luckily i was just testing Zentyal, but when I installed python-apt after
reading the error message, apt seemed to completely break.  I would be
curious on a workaround/fix for this as well.

[ovirt-users] Issues getting agent working on Ubuntu 17.04

[Wesley Stewart]

I am having trouble getting the ovirt agent working on Ubuntu 17.04
(perhaps it just isnt there yet)

Currently I have two test machines a 16.04 and a 17.04 ubuntu servers.


*On the 17.04 server*:
Currently isntalled:
ovirt-guest-agent (1.0.12.2.dfsg-2), and service --status-all reveals a few
virtualization agents:
 [ - ]  open-vm-tools
 [ - ]  ovirt-guest-agent
 [ + ]  qemu-guest-agent

I can't seem to start ovirt-guest-agent
sudo service ovirt-guest-agent start/restart does nothing

Running  *sudo systemctl status ovirt-guest-agent.service*
Aug 08 15:31:50 ubuntu-template systemd[1]: Starting oVirt Guest Agent...

Re: [ovirt-users] Issues getting agent working on Ubuntu 17.04

[Wesley Stewart]

Actually just got it working.

17.04 seems to have version .12-1 of python-ethtool.
I simply removed it and the ovirt agent

sudo apt-get remove python-ethtool

And then I found the same version of python-ethtool on my 16.04 ubuntu
server (0.11-3) and found a deb file for it:

wget http://ftp.ubuntu.com/ubuntu/ubuntu/pool/universe/p/python-
ethtool/python-ethtool_0.11-3_amd64.deb
dpkg -i python-ethtool_0.11-3_amd64.deb

and the reinstalled ovirt
sudo apt-get install ovirt-guest-agent

The GUI is now giving me memory and CPU and indicating that everything is
up to date!

Re: [ovirt-users] Issues getting agent working on Ubuntu 17.04

[Wesley Stewart]

Oddly enough, on Ubuntu 16.04 I had similar issues, but different outputs.
The "fix" for me was pretty much the same.  The oddest part was that apt
reported that python-ethtool was on version 0.11-3.  I removed it and
installed via a deb file anyways.

sudo apt-get remove python-ethool  *(even though reporting 0.11-3, this
also remove ovirt-guest-agent*)
wget http://ftp.ubuntu.com/ubuntu/ubuntu/pool/universe/p/
python-ethtool/python-ethtool_0.11-3_amd64.deb
sudo dpkg -i python-ethtool_0.11-3_amd64.deb
sudo apt-get install ovirt-guest-agent
sudo systemctl enable ovirt-guest-agent.service
sudo systemctl status ovirt-guest-agent.service (now reports as active
(running)!)

[ovirt-users] Need some help understanding memory allocation

[Wesley Stewart]

I am a little confused on why my CentOS box is using so much RAM.  I
currently have a small test setup which only has *12GB* of ram total.

When I log into the administrative interface it tells me:

*Memory*
4.3
Available
of 15.5 GiB
Over commit: 39% (allocated 45%)

11.1 GB Used

Currently I am only running 3 VMs with memory allocations as follows:

Defined Memory:
1024 MB
Physical Memory Guaranteed:
1024 MB

Defined Memory:
3072 MB
Physical Memory Guaranteed:
3072 MB

Defined Memory:
2048 MB
Physical Memory Guaranteed:
2048 MB
*Or 6144MB used by VM*

If I SSH into my ovirt host, and run TOP and sort by memory, the top usage
items are:
31896 qemu  *21.5%* 727:21.44 qemu-kvm
 6008 qemu*14.6%* 190:33.70 qemu-kvm
 3019 ovirt*13.6%*  35:47.64 java
 5800 qemu *8.5%* 784:26.88 qemu-kvm
 2565 ovirt*3.9%*  62:58.00 java

Everything else is pretty small compared, but for the OVIRT/QEMU we roughly
get


*Total: 62% = 7.45GB*
So I am a bit confused as to the Ram being reported to me by the system
(15.5GGB, but the system only has 12GB), and assuming OVIRT is using around
7-8GB, does a bare minimal install of CentOS really need 4-5GB of Ram to
run?

This is a bare minimal install of CentOS7 running only Webmin and oVirt.  I
think there are several things I don't understand here, and I am quite new
to oVirt and would like to learn, so please excuse my inexperience if this
is a silly question!

Thanks either way, I am really happy I ditched my ESXi box :D

[ovirt-users] Issues importing VM from Export Domain

[Wesley Stewart]

I was doing some testing and recently rebuilt my homelab using a Xeon-D
based board.  I did not have anything too important, so I thought this
would be a good chance to test re-importing my backups and seeing how well
it works.

I created a new export domain and copied all of my old VM's into this new
export domain.  But the problem is, the images are in a "Locked" state.
The console tells me:

Aug 13, 2017 11:59:38 PM
Failed to import Vm Clonezilla_Server_BACKUP_20170807_010018 to Data Center

Aug 13, 2017 11:59:37 PM
VDSM OVIRT-Host command HSMGetAllTasksStatusesVDS failed: low level Image
copy failed

This happens for all the VMs shown in the Export-Domain.

I also tried the unlock_entity.sh script, but I am having some postgres
access issues:

unlock_entity.sh -r -t vm -i Clonezilla_Server -s localhost
psql: FATAL:  no PostgreSQL user name specified in startup packet
FATAL: Cannot execute sql command: --file=./unlock_entity.sql

I thought I could just poke around the database by running:

psql -d engine -U postgres

But this also fails
psql: FATAL:  Peer authentication failed for user "postgres"

Was just hoping someone had some suggestions.  I can't event delete
this VM!  Thanks!

Re: [ovirt-users] Issues importing VM from Export Domain

[Wesley Stewart]

I figured out part of it!

After I figured out how to access the DB, I was able to update to correct
entry in the "vm_dynamic" status  to 0.  I did this by:

sudo su postgres

psql engine -c "SELECT vm_guid, vm_name from vm_static WHERE vm_name =
'Clonezilla_Server';"

Returns:0eb29824-f1ca-4d27-bf57-a3ed36c40c18

psql engine -c "update vm_dynamic SET status=0 where
vm_guid='0eb29824-f1ca-4d27-bf57-a3ed36c40c18';"

After this I was able to delete the entry from ovirt. I am not sure why a
disk would not import, but at least I dont have a locked image in the queue
anymore!

[ovirt-users] Import task stuck in 'Tasks'

[Wesley Stewart]

I had an issue importing VMs from an export domain I was trying out.  The
template would fail to copy over, and be stuck in a "paused" state where I
could not delete or modify the VM.  I was able to fix this by dropping into
the SQL database and running:

*psql engine -c "SELECT vm_guid, vm_name from vm_static WHERE vm_name =
'VM_Name_Here';"*


*psql engine -c "update vm_dynamic SET status=0 where
vm_guid='LongStringFromFirstCommand;"*


This was able to set the status to a state where I could delete the VM, but
now I still see the "import" task in the task log.


I did some more database diving and found that if i ran:

*SELECT * FROM audit_log WHERE vm_name = 'VM_Template_Name_Here';*


These entries seem to correspond with the audit entries. Can I simply
delete these entries from "audit_log"? Or would this cause problems?


Or perhaps, to be safe, I should just see if I can set them to "Completed"


As always, thanks!

[ovirt-users] Host non-responsive - All VMs shutdown

[Wesley Stewart]

I have noticed this a couple times now.  digging through the logs, it looks
like the host decided to become unresponsive:

There is a lot more, but I thought dropping it into a pastebin would be
better:

It looks like the host stopped responding somehow but I can't quite tell
how.  Any advice or input would be greatly appreciated!

Re: [ovirt-users] Host non-responsive - All VMs shutdown

[Wesley Stewart]

I saw that, but my entire environment is running on a single host (Even the
data domain is on the same host).  How would it be possible for the host to
basically stop talking with itself?  Isn't that a little peculiar?

[ovirt-users] Task stuck at "Finalizing"

Back when I first installed ovirt a couple months ago, I tried importing

[ovirt-users] Help - Host unresponsive!

[Wesley Stewart]

I have a single server that is running ovirt as a host and a storage
domain.  I ran an update when the GUI told me that there was one.

I shutdown all of the VM's, placed the host in maintenance mode and did the
update.  Upon rebooting the server, I was able to pull my VM's online

well as the host.

The host is showing as "Down" and I cannot "Activate" it.  Also
"Maintenance Mode" is greyed out.

Storage pools are "down" but eventually come back online, but the host
still will not come online.

Every few minutes, the host goes to "UP" right before failing and going
back "Down".  To make it more confusing, like I mentioned before, this is
all in one box, so it isn't like their is a network issue between the
storage and the host boxes or anything.

Currently trying to reinstall the host and see if that helps, but I would
very much appreciate any sort of guidance, support or ideas!

Re: [ovirt-users] Help - Host unresponsive!

[Wesley Stewart]

Thanks for the quick response Charles!  Only had a second so I have not
taken a look at the logs yet...

But after reinstalling the host, it looks like everything came back up at
first.  I have discovered what is causing the entire host to fail, crash
and reboot is when I mess with my windows 10 vm through the graphics card.

I have an old Radeon HD 6870 that I have been using in my windows 10 vm
without issue (I even did some light gaming with no issues).  It seems that
the last update I did has caused not only my windows VM to crash, but also
my entire OVIRT host.

Really not sure why Ovirt has an issue with my graphics card on my windows
host all of a sudden.  Will check the logs soon.

The main login page shows:
Version 4.1.4.2-1.el7.centos

Isn't 4.1.5 out?  My centos7 box wont seem to find the 4.1.4

Re: [ovirt-users] Help - Host unresponsive!

[Wesley Stewart]

I checked under:
/var/log/hosted-engine-ha/

I do not have this directory in my /var/log file.

Also I did some more experiments.  I removed the graphics card and left
only a keyboard and mouse (USB inputs) added to the VM.  Same as before,
everything works fine, but once I try to use the keyboard or mouse

BOOM everything crashes (including the host, which reboots after).   Next
step, I suppose it to try a different keyboard and mouse, but my guess is
that any USB added device will cause the VM and host to crash upon
interaction.  Everything loads fine, and the VM even continues to continue
working normally, until one of these device is activated or used.

Any ideas?

Re: [ovirt-users] Help - Host unresponsive!

[Wesley Stewart]

So it appears that things being passed through VIA USB passthrough are
broken.

My mouse does not seem to register in my Windows 10 VM, and the two
keyboards I have tried have caused the VM and the host to crash.

I am not trying to update my host to 4.1.5 by running "sudo engine-setup"
on my host.  It seems to detect the updates, but then fails saying "[ ERROR
] Failed to execute stage 'Setup validation': Cannot upgrade the Engine
database schema due to wrong ownership of some database entities."

Any ideas?  I am tempted just to blow everything away and start over, but I
dont know how difficult it is to use an old data domain in a new install.
Would it be as simple as copying the files over into the new domain?

Re: [ovirt-users] Help - Host unresponsive!

[Wesley Stewart]

Since I was having issues with updating I decided to just blow away my
ovirt-engine install.

This possessed some challenges, but I basically just ran the script here:
https://www.ovirt.org/documentation/how-to/hosted-engine/

to remove everything.  I also made sure my postgres database was removed.
I also had to run the "ip link del" commands on the ovirtmgmt interface to
make sure it was removed.

After detaching, and re-importing my data domain everything seems to be
working so far.  Keyboard is at least working with no crashes!

[ovirt-users] Mouse USB passthrough not working

[Wesley Stewart]

I have a windows guest that I use to use without issue, but since upgrading
from 4.1.4 to 4.1.6 I cannot get a mouse to pass through to the VM using
USB Passthrough.

Keyboard using USB passthrough and my GPU works without an issue.  I have
tried multiple mice with the same issue, they just wont work.

Any ideas?

Re: [ovirt-users] Mouse USB passthrough not working

[Wesley Stewart]

I did some more testing.  Is it possible ovirt is assigning the incorrect
devices?

I found out that if I don't assign the keyboard to my VM, but still hit
ctrl + alt + delete, everything still crashes! (Host and VM).

I checked the VMs devices:
[image: Inline image 1]

and I also ran lsusb on my host

[image: Inline image 3]

Shouldnt the host have *3_2* & *3_3*, not *3_1 *& *3_2*? even though this
is what the gui has listed for the keyboard and mouse?

Re: [ovirt-users] Mouse USB passthrough not working

Further testing...

Something is definitely odd, after adding everything in the USB Bus 3
things are working fine; Mouse, keyboard, no crashes.  VM has a couple
extra things in the device manager, but since none of my other VM's require
anything USB it is fine for now.  Just found it all odd.

[ovirt-users] How is everyone performing backups?

[Wesley Stewart]

Originally, I used a script I found on github, but since updating I can't
seem to get that to work again.

I was just curious if there were any other more elegant type solutions?  I
am currently running a single host and local storage, but I would love to
backup VM's automatically once a week or so to an NFS share.

Just curious if anyone had tackled this issue.

Re: [ovirt-users] Access via IP instead of FQDN, as well as login issues (cannot authenticate root)

[Wesley Stewart]

Just change your host file on said machine.  If you are on windows, for
example edit
C:\Windows\System32\drivers\etc\*hosts*

and simply add:
IP_ADdress ovirt.domain.com
Now ovirt.domain.com will resolve to the IP address.

Not sure about #2.  I hope I understood correctly.

Bacchus looks really interesting.  I can't quite tell does that run on top
of OVIRT, or can I install bacchus in a separate VM and point to the ovirt
server?  I might give this a try next weekend and see how well it works.

Thanks for all the responses, it is interesting to see all the different
ways people are making this happen.

I used the "wefixit" in the past, but I had trouble getting this to work
since I upgraded to 4.1.6

I also just realized that I am getting a weird error when I try to clone a
snapshot (Just sent a separate email about it which some of you guys might
have seen already).  I think that might be what was causing it to fail.

On a side note, I also went ahead and install Bacchus.  I love the UI and
the interface.  I got my ovirt manager added to Bacchus and it is seeing my
VM's, but when I try to do a manual backup, the site just becomes stuck and
is "spinning".  I think my error on cloning snapshots might also be at play
here.

VM's, but when I try to do a manual backup, the site just becomes stuck and
is "spinning".  I think my error on cloning snapshots might also be at play
here.

Re: [ovirt-users] Cannot clone a snapshot

[Wesley Stewart]

Yep, should have just assumed /var/log

Looks like a javascript issue.  Anyone else having trouble cloning a
snapshot on 4.1.6?

Re: [ovirt-users] Cannot clone a snapshot

[Wesley Stewart]

Woo! I am not crazy.

I always have a hell of a time re-adding my USB passthrough for my keyboard
and mouse (CentOS seems to bluescreen if I press ctrl + alt + del, unless I
add the correct usb devices on the same bus).  So I always try to not
update once I get things stable, but this looks like I will need to.

Thanks for the quick response

Re: [ovirt-users] Cannot clone a snapshot

[Wesley Stewart]

I have a Radeon HD 6870 that I have passed through to a Windows 10 host.  I
decided to build 2 servers using Xeon-D 1528 processors (Super Micro
x10sdv-6c+) in a very small Node 304 mITX form factor. I didnt want a third
box as a desktop, so I have a "desktop" that is actually a Windows 10 guest.

Re: [ovirt-users] Cannot clone a snapshot

[Wesley Stewart]

For a desktop experience?  Well I have an actual monitor, keyboard and
mouse setup.  So I actually go to my desk and log onto my VM like it was a
desktop setup with a monitor mouse and keyboard.

Spice generally works fine for editing the VM or doing basic tasks, but if
I need to do actual work (Office, R, and even some light gaming :D ) the
"desktop" setup works quite well with an oVirt guest with a GPU passed
through.

Re: [ovirt-users] Import VM's from a dead ovirt domain

[Wesley Stewart]

I am quite new to oVirt and only use it at home for the moment.  So I wont
be of much help.

But I was able to add a new export domain, and then copy the original
contents of my old domain into this export domain, which seemed to work
fine.  I just had to hit the "load" button while in the import section of
the web gui (but I am assuming you have done this already).

I have struggled understanding why you cannot simply just point to an oVirt
VM file and import this way, or "import" an export domain that already
exists.

Re: [ovirt-users] ovirt viewer mouse not working

[Wesley Stewart]

You could try passing through a USB Keyboard and mouse if you have spare
USB ports and see if those repond.

You should be able to view the VNC/Spice Viewer and use the USB
Keyboard/mouse to control it.

Re: [ovirt-users] how to clean stuck task

[Wesley Stewart]

You could also go database diving.  I had an issue where I tried to import
a VM from my export domain and it just got hung.  I tried running the
unlock_entity script but it just kept failing.  It sat there for months
stuck, and found
http://lists.ovirt.org/pipermail/users/2015-April/032346.html

Of course deleting something from your database is quite permanent. I would
wait and upgrade to 4.1.7, but something like the below should work. But
probably not recommended

Drop into postgres
psql -d engine -U postgres

List your tasks and grab the job_id
select * from job order by start_time desc;

select DeleteJob('8424f7a9-2a4c-4567-b528-45bbc1c2534f');
Where the string here is the job ID

Re: [ovirt-users] how to clean stuck task

[Wesley Stewart]

Is the VM showing as locked?  You could try to manually unlocking it.  I
did this in a test environment a while back with some success after a vm
was stuck in a "locked" state.  Of course the gui and engine should handle
most of this for you, manually mucking around the internal DB can cause
some pretty serious issues if you are not careful...

sudo su postgres

psql -d engine -U postgres

SELECT vm_guid, vm_name FROM vm_static WHERE vm_name='*VM_Name_Here*';
This should return a string such as: "0ec20854-e1ca-4e49-be87-a6cd36d40c18"

Reset the lock:
update vm_dynamic SET status=0 where vm_guid='
0ec20854-e1ca-4e49-be87-a6cd36d40c18';

[ovirt-users] Strange drive performance over 10Gb

[Wesley Stewart]

I was curious if anyone else has seen this or had any suggestions.

I have recently began playing around with my two servers (Freenas Box and
oVirt box) and their 10Gb Ethernet ports.

I can access the Freenas SMB share over the 10Gb port without issue and I
have been playing around with the capabilities.  After finding out that my
Linux Raid (MDADM) mirror is having horrible write performance, I decided
to plug in an NVMe drive that I had lying around and check out its
performance.

*For my first test*,I added the NVMe drive as a passthrough device to a
Windows guest and was able to transfer to and from Freenas box without
issue.  Speeds were typically ~350-400 MB/s but could drop down to 250 MB/s
or so, and would top out around 525 MB/s, pretty slick!

*For my second test*, I decided to mount the NVMe drive on the CentOS ovirt
host and make it a local datastore.  I migrated my Windows Guest to it, and
decided to test and see what sort of transfer speeds I got and saw some
weird results...

Writing TOO the NAS worked about the same.  Perhaps a little slower but at
least had a steady 250-300 MB/s.

Writing to the Windows Guest had a very "Fast and then slow, fast and then
slow" type of throughput.  I took a few screenshots:

(Writing TO the NAS was fairly consistent)

https://i.imgur.com/jWNNvfp.png


(Writing TO the Windows Guest on NVMe storage)
Sometimes these hit the *low 10-20 MB/s* during the transfer.

Re: [ovirt-users] Strange drive performance over 10Gb

[Wesley Stewart]

I have been fiddling with the drive settings in the windows guest and have
been able to fix a lot of the issue.  I went into Device manager -> Disk
Drives -> (right click) QEMU QEMU HARDDISK -> Policies and checked "*Turn
off Windows Write-Cache buffer flushing on the device*"

I am not sure how safe this is to do in a virtual machine, but my 10Gb
transfer speed is now much more stable.  Occasionally it dips to the low
100 MB/s or so, but generally stays at 200-300 MB/s.

Re: [ovirt-users] How do I connect to my VM from another PC?

[Wesley Stewart]

Did you add the NIC after you did the OS install?  Most installers are
pretty good about detecting and activating NICs when you do the install.
But if you add a NIC afterwards sometimes you have to activate it manually.

What OS is your guest? Version?

If you run "sudo nmtui" does that get you to the text based network manager?

Re: [ovirt-users] Some questions

[Wesley Stewart]

In addition to the previous post, oVirt requires you to use a DNS entry,
not an IP address to access the web interface.  If you don't run your own
DNS server, you can simply edit the host files on the client PCs.  This is
quite easy to do.  For example, just Google "edit host file on Windows".

Did you add the vnic after the installation?  The Linux distros are pretty
good when doing the install of detecting the NICs, but if you add them
later you may have to enable them afterwards.  Try running "sudo nmtui" and
see if you can enable it that way.  Otherwise you will Need to activate it
manually.

Lastly, windows was tricky for me at first.  Have you downloaded the oVirt
driver ISO?  Make sure that you have downloaded this and have it available
for oVirt vms to use.  During the windows install, you will have to use the
"change disk" or "change CD" button in the console once you get to the
point where you can choose your driver's, load the correct drivers, and
then switch back to the windows iso and continue the install.

3. Why when I try to install W10, it doesn't detect any Hard Drive ? I

[ovirt-users] Shutdown all VM's command line

[Wesley Stewart]

Is there an easy way to do this?

I have a UPS connected to my freenas box, and using NUT and UPSC I can
monitor the battery level on my centos 7 host.

In the case of an emergency, and my UPS goes below, lets say 40% battery, I
would like to make a script to shutdown all running VMs, and then reboot
the host.

Otherwise I am afraid of sending a straight reboot command to the host
without taking care of the virtual machines first.

Thanks!

Re: [ovirt-users] Shutdown all VM's command line

Hey,  thanks for sending this to me.  Works like a charm.  I have this tied
in with a UPS script that monitors the UPS on another system, and fires off
your script before a shutdown command.  Works pretty well so far!

I am using the default certificates.   Took me a second to find out where
they are stored, but after pointing directly to it, everything is working
like a champ.

Thanks!

[ovirt-users] Using network assigned to VM on CentOS host?

[Wesley Stewart]

This might be a stupid question.  But I am testing out a 10Gb network
directly connected to my Freenas box using a Cat6 crossover cable.

I setup the connection (on device eno4) and called the network "Crossover"
in oVirt.

I dont have DHCP on this, but I can easy assign VMs a NIC on the
"Crossover" network, assign them an ip address (10.10.10.x) and everything
works fine.  But I was curious about doing this for the CentOS host as
well.  I want to test out hosting VM's on the NFS share over the 10Gb
network but I wasn't quite sure how to do this without breaking other
connections and I did not want to do anything incorrectly.

I appreciate your feedback!  I apologize if this  is a stupid question.

[ovirt-users] Custom ignition in cloud-init?

[Wesley Stewart]

Before anyone tells me this is now included in 4.4.0, I saw this, but I
don't think I'm willing to update my centos7 host to centos8 yet. (But
perhaps that will be the answer).  Currently on 4.3.9/Centos 7

I am trying to run fedora core is to test it out, and the ISO installer
hangs on:
"failed to isolate default target freezing"

So I tried the QCOW2 image, but I'm looking at ways of running the ignition
file.  I see in the "run once" section i can deploy a custom unit script,
and I was wondering is this filetype agnostic?  If I generate a JSON
ignition script and put it in there will it get passed through correctly ?
Or will I need to update to 4.4.0?

I also found:
https://gerrit.ovirt.org/#/c/18/
This was abondoned for a "better solution" last September.  Was this
referring to the changes in 4.4.0?

Lastly has anyone who was running 4.3.9 upgrade their centos host to
centos8 and then upgrade ovirt without any issues?  I usually try and wait
at least a couple of minor version changes before switching to a new major
version.

Thanks guys!

[ovirt-users] Re: RDP

[Wesley Stewart]

Are you asking for troubleshooting on getting windows RDP working in a
windows 10 guest?

Shouldn't have anything to do with ovirt.  Do you have a local admin
account with the same credentials?  That would explain why it works.

To test, make a test user, make it an administrator and try instead of an
RDP user group.  Sounds like a permission issue.

I am trying to add a host to a single host cluster.  Everything has gone

The installation "finishes" and the host goes into a non-responsive state.
I am not really sure where to check.  I get a:

that up to the outside.

Just my two cents.

Are you on 4.1.9?  I didn't have any issues getting up to date on 4.1.9,
but I did have to add the updated gluster repos.

[ovirt-users] Ovirt system crash when starting VM with Quadro GPU

[Wesley Stewart]

I have recently been using an old Radeon R9 270X lying around without
issue, until this card seemed to have kicked the bucket.

I had an Nvidia Quadro P2000 lying around I thought I would try.  After
installing it into my system, it showed up in the PCI device as
anticipated.  I based both devices to my Windows 10 guest.

It shows up a a GP106GL and a separate audio component.  The same thing
that happened with the AMD Radeon Card.  The events just shows the VM's
being terminated without giving a reason, and I am hoping for some
guidance.

Currently using a single node setup, running ovirt 4.2.3.  Any ideas or
places to check would be much appreciated!

[ovirt-users] Re: Docker best practices

[Wesley Stewart]

I'm currently using CoreOS as a VM and I like it.  RancherOS performs
similarly, but appears to have a smaller footprint.

I doubt you will see a big different in performance.  I'm sure ovirt can
handle them both fine.

You can also spin up a RH or CentOS vm and install docker just fine.  But
the smaller footprints are nice.

CoreOS was recently aquired by redhat if I'm not mistaken, so I went with
CoreOS personally.

[ovirt-users] Re: Ovirt system crash when starting VM with Quadro GPU

[Wesley Stewart]

Ended up fixing this by following the ovirt docs (go figure)

https://ovirt.org/develop/release-management/features/virt/hostdev-passthrough/

After following this I also had to reinstall my host as well as reboot.
The OS was not letting go of the device.

Strangely I have done this with two AMD graphics cards and they worked
without this.  Perhaps the drivers weren't installed by default or
something and the OS didn't have trouble passing it along.

Anyways, working happily now with my new quadro p2000 passed to a windows
10 guest. Makes a nice "desktop" at home.

[ovirt-users] NFS Storage Advice?

[Wesley Stewart]

I currently have a NFS server with decent speeds.  I get about 200MB/s
write and 400+ MB/s read.

My single node oVirt host has a mirrored SSD store for my Windows 10 VM,
and I have about 3-5 VMs running on the NFS data store.

However, VM/s on the NFS datastore are SLOW.  They can write to their own
disk around 10-50 MB/s.  However a VM on the mirrored SSD drives can get
150-250 MB/s transfer speed from the same NFS storage (Through NFS mounts).

Does anyone have any suggestions on what I could try to speed up the NFS
storage for the VMs?  My single node ovirt box has a 1ft Cat6 crossover
cable plugged directly into my NFS servers 10GB port.

Thanks!

[ovirt-users] Re: NFS Storage Advice?

[Wesley Stewart]

I have added the "async" option to the "additional mount options" section.

Transferring from my raided SSD mirrors is QUITE fast now.

However, this might be confusing, but if I read/write to the nfs share at
the same time performance plummits.

So if I grab something from the SMB share over 10gb network and write this
to my VM being hosted on the NFS share.  Bad performance.

Or If I copy and paste ISO from the VM to itself, horrible performance.

If I grab a file from a VM on my raised SSD storage and copy it to my VM on
the NFS Share, it has great performance (400+ MB/s)

Not quite sure what's going on!  However if I grab something from the 1gbps
network everything seems okay.  Or if I change the NFS Mount to the 1 gbps
everything is okay.

Any ideas?

[ovirt-users] Re: NFS Storage Advice?

[Wesley Stewart]

Windows reportes about 500-600 MB/s over a 4GB file.

However I believe I found the issue.  My NFS backend is ZFS which is
apparently notorious for horrible sync writes.

https://forums.freenas.org/index.php?threads/sync-writes-or-why-is-my-esxi-nfs-so-slow-and-why-is-iscsi-faster.12506/

I will try an iSCSI target and see how that goes.

[ovirt-users] Re: Reading an ISO image to identify the Image version and type

[Wesley Stewart]

Maybe I am missing something, but can't you just name your ISO files
appropriately?

Windows can read the ESD file in the ISO using DISM, however I do not know
if there is a program in Linux that can parse that info.

I would suspect you are looking for a third party tool somewhere.

[ovirt-users] Passing through Quadro cards to guest

[Wesley Stewart]

Has anyone experimented with this?

I have had really good success with AMD cards, but consumer end graphics
cards fail to load due to NVIDIA blocking them.

I happened to have an NVIDIA Quadro P2000 lying around and I thought I
would give it a shot.  I really like these cards as they only require the
75W provided PCI power.

I can pass the Quadro through just fine, however after a couple minutes of
playing a video, the audio gets really "buzzy" and the video drops to about
3-5 FPS.  This is while doing pretty minimal stuff.  Currently testing with
720/1080 youtube videos.  Card is pulling about 6-10W total.  And otherwise
working fine on my Windows 10 guest.

I have also tried enabling/disabling MSI interrupts which the card supports
without making a difference.

I am running a single host setup:
X10SDV-6c+ (Xeon D - 1528)
running oVirt 4.2.3

[ovirt-users] Anyone have any luck with Bacchus?

[Wesley Stewart]

I am trying to get Bacchus installed:
https://github.com/openbacchus/bacchus

It seems he has upgraded to installing via an ansible playbook.  I can get
this to run all the way through, hopefully NGINX either ends up responding
with a "Gateway error" or it will give me the default nginx landing page.

I have tried with a RHEL7 and CentOS7 VM, as well as in a CentOS\systemd
docker container, all of which having about the same amount of luck.  I was
just curious if anyone else has gotten this to work recently.

interface?  It would be nice to see some type of IOPs data, so we can see
which VMs are hitting our data stores the most.

It seems you can run virt-top on a host to get some of these metrics, but
it would be nice to get some sort of data in the gui.

Thanks!

[ovirt-users] Re: VM Lock state location

[Wesley Stewart]

Definitely don't recommend messing with the DB.

However I have some old notes I took on trying to change the lock
status This was probably on 4.1 or early 4.2, so YMMV.

Use at your own risk.  No official documentation will ever tell you to go
DB diving, and for good reason.

sudo su postgres

psql -d engine -U postgres

psql engine -c "SELECT vm_guid, vm_name from vm_static WHERE vm_name =

Returns:0eb29824-f1ca-4d27-bf57-a3ed36c40c18

psql engine -c "update vm_dynamic SET status=0 where
vm_guid='0eb29824-f1ca-4d27-bf57-a3ed36c40c18';"

[ovirt-users] Migrated disk from NFS to iSCSI - Unable to Boot

[Wesley Stewart]

This is a new one.

I migrated from an NFS share to an iSCSI share on a small single node oVirt
system (Currently running 4.3.10).

After migrating a disk (Virtual Machine -> Disk -> Move), I was unable to
boot to it.  The console tells me "No bootable device".  This is a Centos7
guest.

I booted into a CentOS7 ISO and tried a few things...

fdisk -l shows me a 40GB disk (/dev/sda).
fsck -f tells me "bad magic number in superblock"

lvdisplay and pvdisplay show nothing.  Even if I can't boot to the drive I
would love to recover a couple of documents from here if possible.  Does
anyone have any suggestions?  I am running out of ideas.

[ovirt-users] Re: Migrated disk from NFS to iSCSI - Unable to Boot

[Wesley Stewart]

I think I figured this one out.  Looks like the disk format changed when
moving to block storage.  The VM template could not cope with this change.
I deleted the VM, and attached the disk to a new VM, and everything worked
fine.

In pretty sure all of 4.3 is compatible with RHEL7 and Centos7.

I haven't tried the specific versions myself though.

This is a little concerning.

But it seems pretty easy to convert:

However I would be curious to see if someone tests this with having an

[ovirt-users] Single Node 4.3 to 4.4 help

[Wesley Stewart]

I have read through many posts and I think this process seems fairly simple.

https://www.ovirt.org/documentation/upgrade_guide/#SHE_Upgrading_from_4-3

But I just wanted to see if anyone had any gotchas.  I am thinking of
either using

   - RHEL8 (Using developer program, probably best best atm)
   - Ovirt Node (Is ovirt node being deprecated since it is based on
   centos?)
   - Rocky Linux/AlmaLinux/Clear Linux

>From my understanding I should:

   - Enter global maintenance
   - Make a full engine backup
   - Reinstall to a supported OS
   - Deploy ovirt engine using backup.

Looking forward to trying out Ovirt 4.4!

[ovirt-users] Re: Ovirt VNC Server

[Wesley Stewart]

So your VM has IP address 172.1.1.1 and it is running a VNC server?  I do
not believe this is an oVirt issue, it sounds like a VNC issue.

On the VM hosting the VNC server, try checking Netstat to make sure that
VNC is listening.

netstat -tulpn


Once you get the port number, make sure your firewall is allowing the port
as well.

You can also setup the VNC configuration in Guacamole's web interface.  I
run CoreOS as a guest and I have a guacamole instance setup in docker that
I use.

Whoops, I realize now that you are trying to connect to the oVirt VNC

Maybe it would be easier to just run VNC on the server you want?

[ovirt-users] Re: Can't install windows guest

[Wesley Stewart]

Couple things...

1.). You created a drive correct?  Just wanted to make sure you did add a
drive.

2.) Once you get to that window in the windows setup to choose your install
drive you need to go to your oVirt console and select "Change Disk" and
change it to the virtio iso that contains drivers.

Once you do this you need to "browse" and find the correct driver. The
drive won't show until you load the correct driver.  After you do this the
drive shows.  Select the drive and go back into the oVirt console and hit
"Change Disk" and choose the windows iso again and continue

[ovirt-users] Re: GPU passthrough

[Wesley Stewart]

I actually use an oVirt VM as my desktop at home.  Why?  Because I can and
I didn't want to have to buy another box for my desktop.  However there are
a few caveats to this and some lessons I learned.

The consumer grade GTX cards are going to have issues being passed
through.  NVIDIA blocks this in their drivers and RedHat honors NVIDIA's
requirements for this.  You can enter an agreement with NVIDIA, which I am
sure costs some money somewhere, to get special drivers.  Or you can use
their enterprise Quadro cards, however I tested a P2000 and could not get
it to work on oVIrt.  But I did not try very hard.

At home, I am using an AMD Radeon RX 480/580.  AMD doesn't care if you pass
it through and it works almost right out of the box.  You just want to make
sure to blacklist the AMD drivers for the host, and put them in the
PCI-Stubs group.  It's really easy with some basic bash/terminal knowledge:
https://ovirt.org/develop/release-management/features/virt/hostdev-passthrough.html
Check the physical GPU portion.

You can, HOWEVER, trick the VM into not thinking it's a VM in KVM and
QEMU.  To prove this, I built a proxmox box at work to test it and I was
able to successfully pass through a GTX 1060 without too much trouble.  I
Have some notes here:
https://docs.google.com/document/d/1vlOIbJ4iXE7ypdSJ0OWQZfgcG9dEx2_PxXh6oRjl878/edit?usp=sharing
However these are pretty rough notes.  I just wanted to prove it could be
done.

For oVirt a lot of the QEMU/KVM settings and commands are going to be
stored in databases and files.  and I had trouble getting these to pick up
on the oVirt side.  I even tried creating a VDSM hook, as mentioned in this

But I never got it working.

I am definitely no expert, but I have done a lot of tinkering with this.
But you will get pushback from oVirt/Redhat as this is not officially
supported.  If you want it to work with consumer grade cards, use AMD.  If
you want to do it "right" you will have to buy the enterprise quadro
cards.  But these get quite pricey.

[ovirt-users] Changing from thin provisioned to preallocated?

[Wesley Stewart]

I am currently running a ZFS server (Running RaidZ2) and I have been
experimenting with NFS and shares to host my guests.  I am currently
running oVirt 4.2.8 and using a RaidZ2 NFS mount for the guests.

ZFS definitely is definitely pretty awful (At least in my experience so
far) for hosting VMs.  I believe this is due to the synchronous writes
being performed.  However, I think running an iSCSI target with
Synchronization disabled over a 10Gb connection might do the trick. (I have
a couple of mirroed SSD drives for performance if I need it, but the RaidZ2
crawls for disk speed).

When I tried to migrate a thin provisioned guest to iSCSI, I keep getting
an "Out of disk space error" which I am pretty sure is due to the block
style storage on the iSCSI target.  Is there a way to switch from Thin to
Preallocated?  Or is my best bet to try and take a snapshot and clone this
into a pre-allocated disk?

[Wesley Stewart]

 Appreciate the response!

But there is plenty of space available.  About 250 free GBs. My test VM is
about 40gb.

[ovirt-users] I'm in trouble....

[Wesley Stewart]

Luckily this is for a home lab and nothing critical is lost.  However I was
trying to change the subnet my host was on.  And I found out that you
cant do that.  So I reverted back but my hosted engine wasnt happy about my
NFS mounts.

so I did a engine-cleanup and an engine-setup.  Went through the prompts
and thought nothing of it.  I logged back into ovirt, and everything looks
like it was a brand new install.  No VMs or anything.  I believe I have a
fairly recent backup somewhere... trying to track that down, but it's not
looking good.

Currently running 4.3.10.  I have been planning out my 4.4 upgrade
anyways.  I would prefer to not start from scratch... but if I do it is not
the end of the world, will just take a lot more time.

Looking for some guidance! Thank you.

[Wesley Stewart]

I believe I should have the dump from the initial engine-setup.  Can that
be used?

Also, I'm only running about 8 vms and need to start over for 4.4.  Would
it be easier to just reinstall and import the disks?

I appreciate the quick replies.  Yes very basic.  Single host/node with NFS
and local storage.

I will try to reinstall the host and import.  I haven't had to do this yet!

Has anyone tried the open shift upstream old?  Looks like they support
virtualization now.  Which I'm guessing is the upstream for openshift
virtualization?

Good insight.

I use containers a lot, but the virtualization sections are surely
separate?  I might have to try out a node and see how it goes.
