OK.

I suggest, then, that you methodically plan, document and test your
environment on various different failure modes.

Since you are new to oVirt, it's obvious you still do not have the
full mental image of all the components, their behaviour, etc., and
even more so how they might react, or be handled, in emergency situations.
In particular, spend some time learning about the SPM, master storage
domain, HA VMs and how they might be affected by/affecting restore flows,
etc. Good luck!

oVirt does not supply, nor endorse, a specific "preferred method" for this.
Rather, it exposes an API, and provides a simple example script:

https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/vm_backup.py

There are several backup products/projects, both large and small, both
open and closed source, that use this API and can be used. I personally
never used any, so can't recommend anything. If you search a bit the list
archives you'll find at least some of them.

[ovirt-users] Re: Windows Sluggish Performance

[Vijay Sachdeva]

Hey,

 

The problem what I have found is when I am using SPICE as default console 
option, the  console performance is very sluggish. So what I understand here is 
one needs to install additional spice guest tools to improve the performance as 
it includes QLX video driver.

 

https://www.spice-space.org/download.html

 

The moment I switched to VNC console options, performance improved but not far 
better as it should be when taking a console of machine.

 

So still any suggestions to improve console access?

 

Thanks

 

Vijay Sachdeva

I'm using QLX, and despite being sluggish, when you tune windows for best 
performance -it is workable.

Of course, if you passthrough a GPU, performance will be completely different.

Hi Vijay,

Have you tried to run something in the VM?
I want to understand if the performance of the VM is slow, or just the
console access seems to be slow.

Thanks in advance,

[ovirt-users] Re: Scenario: Ovirt-engine on hardware and recovery

[Jayme]

Take a look at vProtect for backups.  Works really well for our
environment, and supports incremental backups as well which is very handy.
It's free for up to 10 VMs to try.

[ovirt-users] Re: Scenario: Ovirt-engine on hardware and recovery

[Robert Webb]

Didi,

Thanks for the reply.

Yes, backups are done, I am just thinking in the case of Murphy's Law where 
nothing works and the engine is gone. I am also new to oVirt and am always 
loking for the "proper" backup method as you have laready mentioned using 
engine-backup.

Storage is NFS backed and backups are done in case of storage server failure.

What is the preferred VM backup method so both disk and VM config is captured? 
Would rather not have to put agents on all the VM for OS level backups and then 
have to manually recreate all of the machines. Do all the VM configs get stored 
on the shared storage just like one of the other virtualization vendors?

Appreciate the time from folks on the list who respond.

You do take backups, right? :-)

For the engine itself, you can use engine-backup.

You didn't mention your plans re storage.

If you put your VMs on well-handled storage, and lose everything but
the storage, you can install a new engine, new nodes, and then import
the VMs from the existing storage. You will still miss some
configuration etc., but should mostly be ok.

If you plan to use gluster storage using the same nodes, aka HCI, the
same applies, obviously, only that the nodes are your storage, and not
an external system. You still have to make sure you handle them
properly - backup, DR, etc., depending on your needs and budget.

If you do have engine-backup backups, but lost all your storage,
engine-backup will not help you.

That's ok, but is not relevant. Main question is the storage. Can be
external or local/gluster with either ovirt-node or EL.

[ovirt-users] Failed export to OVA

[Geoff Sweet]

I'm currently running a stand alone server on 4.2.0.2-1.el7.centos. I know
this is an older version and I am trying to do some exports for migrations
off of it.  The Export to OVA seems simple enough but it fails consistently
and I really can't figure out why.  The logfiles don't provide a lot of
information that speaks to me.  I double checked the known bug (of older
versions) to make sure there is a description set for the disks associated
with the VM.  I also tried to look in the Ansible logs referenced below but
no such log exists.  I've also tried multiple different paths for the
output. All with the same failure. Below you can see I am attempting to
export to /tmp/.  Here is the output of the engine logs:

Hi Gal,

 

I have downloaded the virtio-win_x86.vfd  and uploaded to ISO domain. Used Run 
Once and attached the floppy drive, while looking for drivers in A drive it

Make sure that you attach the latest virtio-win vdf (the link I sent earlier

please open a bug on virtio-win project and send me the url so I will track it,

HI Vijay,

 

There a package on fedora:

virtio-win-0.1.173-2

which contains an MSI installer for the drivers and the ovirt agent (which is 
disabled on a normal installation, so please enable it when you install).

 

This installer should replace the ovirt-wgt that we have currently on the next 
versions,

and it is new, so please give us feedback once you used it.

 

P.S

the installer installs the drivers normally so if the regular drivers from 
virtio-win fail to install, then using the installer will not change much 
probably, and it means that you have a deeper problem.

In case the installation fails then please generate logs but running the 
installer through cmd.exe "msiexec /i {installer} /l*v {path to log}" 
(https://www.advancedinstaller.com/user-guide/qa-log.html)

and open a bug/reply here and I will try and help

 

Thanks

[ovirt-users] Re: Windows VirtIO drivers

[Strahil Nikolov]

 Usually I add a small disk of type virtio and another NIC (also virtio).Then 
if you install , you set the windows DVD as bootable and once you reach the 
moment to select your disk , you have an option to search in a DVD for 
drivers.Then you go to Admin Portal , select your VM and from the 3 dots (up 
right, next to the "Create snapshot" use the "Change CD" to load the DVD iso 
with the tools.
I think that the rpm "ovirt-guest-tools-iso" is providing that (but I don't 
remember it).
Once you  have the DVD loaded, just browse and install the drivers from it.When 
you complete that, "Change CD" again to the Windows Install iso and select the 
disk you want to install your Windows.

[ovirt-users] Windows Sluggish Performance

[Vijay Sachdeva]

Hello Everyone,

I managed to install Windows Server 2016 server on Ovirt node using ovirt
engine.All virtio-Win drivers also installed, but the performance of
Windows using console is very sluggish and mouse pointer is not at all
responsive.

Can anyone let me know, what could be the reason. Not able to to even add
IP to VM as mouse doesn’t work at all.

[ovirt-users] Sigh... still vdsmd memory leak

[Chris Adams]

I've seen vdsmd leak memory (RSS increasing) for a while, and never
gotten anywhere with diagnosing it.  I upgraded a small setup (2 hosts
with hosted engine and iSCSI SAN) last week to 4.3.7 plus latest CentOS
7.7 updates, and I am still seeing this.

Currently, there are only 3 active VMs, plus the engine, all running on
one of the two node (which is also the SPM), and vdsmd on that node is
up to 450M RSS (6 days after upgrading), which is up almost 100M in the
last 24 hours.  On the other node, vdsmd RSS has not changed in the last
24 hours (83M).  I have a script watching the RSS on the growing node,
and it's a pretty steady increase:

   07:59:59.735  452080  +28
   08:00:03.361  452104  +24
   08:00:04.852  452112  +8
   08:00:21.088  452116  +4
   08:00:25.456  452120  +4
   08:00:25.753  452124  +4
   08:00:34.219  452132  +8
   08:00:35.866  452136  +4
   08:00:44.360  452140  +4
   08:00:51.213  452144  +4
   08:00:57.046  452152  +8
   08:00:59.855  452160  +8
   08:01:01.461  452164  +4
   08:01:04.615  452168  +4
   08:01:10.544  452172  +4
   08:01:11.003  452180  +8
   08:01:13.826  452184  +4
   08:01:14.737  452188  +4
   08:01:15.002  452192  +4
   08:01:21.350  452196  +4
   08:01:29.870  452200  +4
   08:01:34.995  452208  +8

This is a problem I have in multiple oVirt setups - don't know if it is
just something about how I installed or what, but I'd really like to
work on getting this figured out and fixed.

Hi, 

I use awx rpm from awx.wiki and followed your directions to create a python2

Hello gianluca, 

I reported this issue a long time ago (march of 19) in an unofficial rpm awx 
project 


[ https://github.com/MrMEEE/awx-build/issues/72 | 
https://github.com/MrMEEE/awx-build/issues/72 ] 




But I see that it is marked as closed

It's marked as closed for the unofficial RPM project only, not with the regular

All related RHV/ovirt stuff (not only dynamic inventory, but all ovirt* ansible

BQ_END

You mean inside awx container, correct? 
See below my comments, as I know almost nothing about venv concepts... sorry 

BQ_BEGIN



What you need to do is create a py2.x venv then recompile latest pycurl with 
nss support like this: 

* # /opt/rh/rh-python36/root/usr/bin/awx-create-venv (-e 
/var/lib/awx/venv/) -n ovirt 

BQ_END

I have to run this inside awx container as user root? Can you explain the 
syntax? I get error because of the parenthesis... 

BQ_END


sure inside the container, parenthesis are the default parameters so you can 
use an other path: 

/opt/rh/rh-python36/root/usr/bin/awx-create-venv -n ovirt -p 2 

BQ_BEGIN



BQ_END


BQ_END

In my awx container I don't have 
/opt/rh/rh-python36/root/usr/bin/awx-create-venv and don't have awx-create-venv

Subject: Re: [ovirt-users] Windows VirtIO drivers

 

HI Vijay,

 

There a package on fedora:

virtio-win-0.1.173-2

which contains an MSI installer for the drivers and the ovirt agent (which is 
disabled on a normal installation, so please enable it when you install).

 

This installer should replace the ovirt-wgt that we have currently on the next 
versions,

and it is new, so please give us feedback once you used it.

 

P.S

the installer installs the drivers normally so if the regular drivers from 
virtio-win fail to install, then using the installer will not change much 
probably, and it means that you have a deeper problem.

In case the installation fails then please generate logs but running the 
installer through cmd.exe "msiexec /i {installer} /l*v {path to log}" 
(https://www.advancedinstaller.com/user-guide/qa-log.html)

and open a bug/reply here and I will try and help

 

Thanks

 Hi,

 I've a fresh new install of ovirt 4.3 and tried to import an gluster
 vmstore. I managed to import via NFS the former data domain. The
 problem
 is that when I moved the disks of the vms to the new ISCSI data domain,
 I got a warning that sparse disk type will be converted to qcow2 disks,
 and after accepting, the disks were moved with no error.

 The problem is that the disks now figure as <1Gb size instead of the
 original size and thus, the vms fail to start.

 Is there any way to recover those disks? I have no backup of the vms :-(

TBH, to help, bug reports are probably the most useful. Having
feedback from users with "real world" setups
and usage will help us improve. As stated before, our biggest issue at
the moment is packaging, once it's handled
it will be significantly easier to test and develop.
Standalone cinder domains were never actually supported (never left
tech preview), we do not have immediate plans
for an upgrade path, but you can definitely submit an RFE for this

We added better cleanup for migration cleanup to handle the bug.
There is another issue which was not known at the time with multipath
preventing unmapping rbd devices[1], and it might be what you
experienced.
This can be fixed manually by blacklisting rbd devices in multipath
conf, but once the bug is fixed vdsm will handle configuring it.

The current plan to integrate ceph is via cinderlib integration[1]
(currently in tech preview mode) because we still have no packaging
ready, there are some manual installation steps required, but there is
no need to install and configure openstack/cinder



1. Does this require you to install OpenStack, or will a vanilla Ceph 
installation work?

a vanilla installation will work with cinderlib


2. Is it possible to deploy Ceph on the same nodes that run oVirt? (i.e. is a 
3-node oVirt + Ceph cluster possible?)

I haven't tried it, but should be possible


3. Is there any monitoring/management of Ceph from within oVirt? (Guessing no?)

No, cinderlib is storage agnostic


4. Are all the normal VM features working yet, or is this planned?

Most features (starting/stopping/snapshots/live migration)  are
working, but not all are fully tested (specifically snapshots)


5. Is making Ceph a first-class citizen (like Gluster) on oVirt on the roadmap?

Not at the moment, maybe once cinderlib integration matures and we
have more feedback and users for the feature

What can we do to help advance Ceph integration in oVirt?

Will standalone Cinder storage domains still be supported in oVirt 4.4?
Will there be a migration scenario from standalone Cinder to cinderlib?

Accidentally just yesterday I had an incident in our test environment 
where migration of a VM with MANAGED_BLOCK_STORAGE (=cinderlib) disks

You do take backups, right? :-)

For the engine itself, you can use engine-backup.

You didn't mention your plans re storage.

If you put your VMs on well-handled storage, and lose everything but
the storage, you can install a new engine, new nodes, and then import
the VMs from the existing storage. You will still miss some
configuration etc., but should mostly be ok.

If you plan to use gluster storage using the same nodes, aka HCI, the
same applies, obviously, only that the nodes are your storage, and not
an external system. You still have to make sure you handle them
properly - backup, DR, etc., depending on your needs and budget.

If you do have engine-backup backups, but lost all your storage,
engine-backup will not help you.

That's ok, but is not relevant. Main question is the storage. Can be
external or local/gluster with either ovirt-node or EL.

Good luck,

[ovirt-users] Re: Upgrade ovirt from 3.4 to 4.3

[Luca 'remix_tj' Lorenzetto]

Hello,

as far as i remember from my certification course, ovirt/rhv 3.5 is
still based on 6. So you can easily upgrade in place and then make
detach/attach.

[ovirt-users] Re: Upgrade ovirt from 3.4 to 4.3

[lu . alfonsi]

I have found also this topic:

https://access.redhat.com/articles/1390733

"RHEV 3.5 supports both RHEL6 and RHEL7 hosts (RHEL or RHEV-H). It is 
recommended to upgrade your hosts to RHEL7 once on RHEV 3.5."

If this is true i could make an update of the hypervisors 6 and not a reinstall 
with centos 7 to reach the 3.5 release...After this as you suggest i can do a 
storage domain detach from 3.5 in order to attach to a new 4.3 enviroment...
