I have yet to figure that one out. All of the VM's I built I had to go old 
school with the tab key and arrow keys...

Very annoying..

Any idea what I need to do to get a working mouse in a Windows VM?  I can click 
on the SPICE viewer but the mouse pointer is fixed to the left hand border.

I just noticed something funny in the Windows installer.  When you get to the 
point where it can't find any installation media, if you Load Driver, a popup 
appears with a Browse and OK/Cancel options.  I assumed that I should be 
browsing to the floppy here but if you do that, you get an error that no signed 
drivers can be found.  Instead, you just have to hit OK when the popup appears 
and that somehow finds the drivers.

I'm assuming that I will need to install the network driver once the 
installation has finished?

It does work that way.

I found that out as I was testing oVirt and had not created a separate ISO
Domain. I believe it was Strahil who pointed me in the right direction.

So if one does not have an ISO Domain, it is no longer required. Along with
the fact that ISO Domains are or in the process of being deprecated.

Don't think you have to use the ISO Domain any longer.

You can upload to a Data Domain and when you highlight the VM in the
management GUI, select the three dots in the top left for extra options and
there is a change cd option. That option will allow for attaching an ISO
from a Data Domain.

That is what I recall when I was using oVirt a month or so ago.

Hi,

it seems the online documentation regarding the windows installation steps
is well out of date.  Where is there any current documentation on where to
get the VirtIO drivers for a Windows installation?

From a bit of Googling, it seems that I need to 'yum install virtio-win' on

that correct?

Where is the documentation maintained and how do I open a bug on it?

What about going in Admin portal, select the VM, and then click the 3 dots

There should be a 'Eject' and all your ISOs (I have already migrated to data

No.

I am using the Spice viewer and my Data domain is on NFS. When I open the

I haven't found any other way to actually mount an ISO to a VM other then the

mount an ISO to a cdrom in the VM config and it shows up in the OS.

Hi.

ISO domains were deprecated. Now you should use a Data Domain instead and fill 
with the ISOs.

If you still using ISO Domain, like me, I only scp the ISOs directly to the 
storage. You don’t need to use the ISO uploader script. I never made it work 
anyway LOL.

https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environment.html

I moved the backup file to my new engine.
How do I perform the restore?

The directions say:

# engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --provision-dwh-db --restore-permissions

What is the file name and log_file name?  Do I need to do something to unpack

Hey folks,

I created a new cluster with a new engine, everything is green and

I do have a backup of the /images/ directory from the old installation.
I tried copying (and preserving user/ permissions) into the new images
gluster dir and trying a domain -> scan to no avail.

What is the correct way to introduce oVirt to "new" (or unknown) images?

Subject: [ovirt-users] Reimport disks

Hey folks,

I created a new cluster with a new engine, everything is green and
running again (3 HCI, Gluster, this time Gluster 7.0 and CentOS7 hosts).

I do have a backup of the /images/ directory from the old installation.
I tried copying (and preserving user/ permissions) into the new images
gluster dir and trying a domain -> scan to no avail.

What is the correct way to introduce oVirt to "new" (or unknown) images?

-Chris.

I guess you had wrong permissions and ownership on the storage before, but vdsm 
was not detecting
the issue because it was missing validations in older versions. Current version 
is validating that creating

Host shouldn't need to be in maintenance mode to add logical networks. I don't

Thanks so much for your reply Robert!

I like your set-up alot, that's where I'm going too actually.  But now I have 
only one node, I'm trying to learn very basic setup with just the one for the 
moment (Because I have it running after years of trying! It will take a few 
weeks and another motherboard / rebuild before I have the second node, I'll get 
there soon).

I've just learned (I think) that I can't sync new logical networks with the 
host, because I can't put the only host in maintenance mode...I thought that 
there might be a way with cli and restarts and all that but lo, there no point, 
I will have another node in a few weeks or months :)

That's okay, I'm trying to work out why I can't access my new test server from 
WAN.  I use split dns with pfsense and haproxy reverse redirects. I can get to 
the server test pages from LAN via the pfSense dns resolution (LAN) but the 
reverse redirects are not working from WAN.  I don't know what next step to 
take to debug the problem.  The engine is accessible from WAN, so I think it 
should work for the vm server, which is also on the default ovirt management 
network and uses all defaults like the hosted engine.  I suspect that there is 
a security setting on the engine, logical network or maybe the server?

What should I check next?

My singe node, is also in the same condition, which may be instructive to a 
noob like me...the node I can reach from the LAN but not the WAN.  So the 
engine is a special case.  Do I need to create certificates on the vm webserver?

I'd like to see if I can set-up a NextCloud server after trying a SuiteCRM 
server.  But I started with fedora 31 server and a very basic lamp stack to 
limit variables...

Thanks in advance.  Let me know if I can ever help you with anything!  I'm an 
Architect, but a real one; not IT but bricks and all that :)

[ovirt-users] Re: High level network advice request

[Robert Webb]

Given what you have described, it seems to be either a HAproxy or server config 
issue. If the server can reach the internet, that solves default gateway 
issues, if you can reach the server from the LAN then that solves any 
networking issues.

I would probably do a packet capture at the pfSense box and on the server to 
see where they stop. It can also tell you if there may be some kind of haproxy 
issue where the translation may not be what you expect.

Thanks again Joseph,

I do have specific noob question.  I'm learning so much with this test 
deployment :) 'Amazing.

I can't get to a test vm / webserver managed by Ovirt Engine from WAN, as I do 
with the Engine and other machinesI suspect that I am missing some pretty 
basic setup step with security but I don't know what to check next?

So I use pfSense with haproxy add on, which is pretty great.  Squid might be 
better, but haproxy was really easy for me to set-up without mastering config 
syntax...

My pfSense is on a physical box at the gateway as a gateway serverso not a 
vm.

I have a working vm on an ovirt node manged / created with engine.  I set up 
the vm with fedora 31 server then added a lamp stack with mariadb & etc.

I can access (from LAN only, not from WAN) the server test page and a text php 
info page that I made.  I don't know what to adjust to debug the problem.  I 
suspect security / firewall issues but not with the pfSense / haproxy reverse 
redirect, I think that's all fine.  I use pfSense DNS Resolution in the LAN as 
split DNS.  Other machines, including the hosted engine machine are accessible 
from WAN using URLs / FQDNs.
My engine for testing is engine.metrodesignoffice.com
The test server is mdowebserver.metrodesignoffice.com

What should I look at next?  I only installed one node so I can't sync new 
logical networks or vnet profiles as I understand (the single node can't be 
placed in maintenance mode, for obvious reasons?).

[ovirt-users] Windows Server Migration from Proxmox

I have successfully imported the disk image into oVirt and attached to a new VM

When I power on, though, they all give me a "kmode exception not handled".

Has anyone else run into this and successfully migrated a WIndows VM? These are

[ovirt-users] Re: High level network advice request

[Robert Webb]

As Joseph mentioned in his email, it is mostly situational dependent.

I run a 2 node cluster and use multiple interfaces.

The first 1Gb nic is for ovirtmgmt and is used for management with no vlan 
tagging and has the default gateway, DNS, etc assigned to it. 

My 2nd 1Gb NIC, for now, is for all VM traffic and from the switch is setup as 
a trunk and carries multiple vlans to the various VM's.

My 3rd NIC is 10Gb and it is on its own isolated vlan with no routing and I use 
it for connectivity to my back end NFS storage and I made it the interface for 
VM migration between nodes.

An additional 10Gb  nic is not in use right now, but plans are that once I can 
get a switch with more 10Gb connectivity, that will become my interface for all 
VM traffic.

So as you can see, very situational dependent.

As Joseph also mentioned, please feel free to ask if you have any questions. I 
am still pretty new to oVirt, but making progress.

Robert

Hi Robert,

I'm just speculating, but maybe the package on the oVirt is too new or too old ?

What version is your Foreman ?

Have you tried to downgrade/upgrade the packages for the integration between 
the 2 systems ?

[ovirt-users] Re: oVirt and Containers

[Robert Webb]

Jan,

Thanks for taking the time for a great reply.

For what I am trying to accomplish here in my home lab, it seems that OKD is 
the safest path. If I understand correctly, with OKD, I just need to build full 
vm's in the oVirt environment which will become hosts, compute nodes, for 
containers that get deployed. OKD is basically just container management and it 
does not care whether or not the compute nodes are VM's or bare metal.

Again, thanks for taking the time to educate me.

Robert

Subject: Re: [ovirt-users] oVirt and Containers

Okay, so this topic is quite vast, but I believe I can at the very least give 
you a few pointers and maybe others might chime in as well.

Firstly, there's the Kubevirt project. It enables you to manage both 
application containers and virtual machines workloads (that cannot be easily 
containerized) in a shared environment. Another benefit is getting advantages 
of the powerful Kubernetes scheduler. I myself am not too familiar with 
Kubevirt, so I can only offer this high-level overview. More info here: 
https://kubevirt.io/

Then there is another approach which I am more familiar with. You might want to 
use oVirt as an infrastructure layer on top of which you run containerized 
workflow. This is achieved by deploying either 
OpenShift<https://www.openshift.com/> or the upstream project 
OKD<https://www.okd.io/> in the oVirt virtual machines. In that scenario, oVirt 
VMs are considered by OpenShift as compute resources and are used for 
scheduling containers. There are some advantages to this setup and two come 
into mind. Firstly, you can scale such OpenShift cluster up or down by 
adding/removing oVirt VMs according to your needs. Secondly, you don't need to 
set up all of this yourself.
For OpenShift 3, Red Hat provides detailed guide on how to go about this. Part 
of that guide are Ansible playbooks that automate the deployment for you as 
long as you provide required variables. More info here: 
https://docs.openshift.com/container-platform/3.11/install_config/configuring_for_rhv.html
When it comes to OpenShift 4, there are two types of deployment. There's UPI - 
user provisioned infrastructure. In that scenario, you prepare all the 
resources for OpenShift 4 beforehand and deploy it in that existing 
environment. And there's also IPI - installer provisioned infrastructure. This 
means that you just give the installer access to your environment (e.g. AWS 
public cloud) and the installer provisions resources for itself based on 
recommendations and best practices. At this point, neither UPI nor IPI is 
supported for oVirt. However there is a GitHub 
repository<https://github.com/sa-ne/openshift4-rhv-upi> that can guide you 
through UPI installation on oVirt and also provides automation playbooks for 
that. I have personally followed the steps from the repository and deployed 
OpenShift 4.2 on top of oVirt without any major issues. As far as I remember, I 
might have needed occasional variable here and there but the process worked.

Hope this helps!
Jan

After doing so, sanlock had no access to the directories and neither did 
libvert. Leaving everything else alone, I changed the the perms to 0760, 
sanlock no longer complained, but libvirtd still complained about file 
permissions.

Next test was to the change file perms to 770 and I got the same error with 
libvertd.

I have not done any linux work for quite a while so please correct me, but if I 
do a "ps aux | grep libvirt" I see the libvritd process running as root. Does 
the libvirt user get invoked only when a script is running? If the daemon is 
only running as root, then would it not be trying to access storage as root at 
this point?

This is my ps list:

root  2898  0.1  0.0 1553860 28580 ?   Ssl  14:45   0:01 
/usr/sbin/libvirtd -listen


Here is what I see in the audit log:

[Robert Webb]

It also appears that sanlock needs AT LEAST rw permissions on the group as rx 
breaks it per logs.

[ovirt-users] Hosted Engine Failover Timing

[Robert Webb]

So in doing some testing, I pulled the plug on my node where the hosted engine 
was running. Rough timing was about 3.5 minutes before the portal was available 
again.

I searched around first, but could not find if there was any way to speed of 
the detection time in order to reboot the hosted engine quicker.

Right now I am only testing this and will add in VM's later, which I understand 
should reboot a lot quicker.

[ovirt-users] Re: HCL: 4.3.7: Hosted engine fails

[Robert Webb]

I could not find if that CPU supported SSBD or not.

Log into one your nodes via console and run, "cat /proc/cpuinfo" and check the 
"flags" section and see if SSBD is listed. If not, then look at your cluster 
config under the "General" section and see what it has for "Cluster CPU Type". 
Make sure it hasn't chosen a CPU type which it thinks has SSBD available.

I have a Xeon X5670 and it does support SSBD and there is a specific CPU type 
selected named, "Intel Westmere IBRS SSBD Family".

Hope this helps.

Hey all,

Using a homogeneous ovirt-node-ng-4.3.7-0.20191121.0 freshly created
cluster using node installer I am unable to deploy the hosted engine.
Everything else worked.

In vdsm.log is a line, just after attempting to start the engine:

libvirtError: the CPU is incompatible with host CPU: Host CPU does not
provide required features: virt-ssbd

I am using AMD EPYC 7282 16-Core Processors.

I have attached

  - vdsm.log   (during and failing the start)
  - messages   (for bootup / libvirt messages)
  - dmesg  (grub / boot config)
  - deploy.log (browser output during deployment)
  - virt-capabilites (virsh -r capabilities)

I can't think -or don't know- off any other log files of interest here,
but I am more than happy to oblige.

The odd thing is the hosted engine vm does get started during initial
configuration and works. Just when the ansible stuff is done an its
moved over to ha storage the CPU quirks start.

So far I learned that ssbd is a mitigation protection but the flag is
not in my cpu. Well, ssbd is virt-ssbd is not.

I am *starting* with ovirt. I would really, really welcome it if
recommendations would include clues on how to make it happen.
I do rtfm, but I was unable to find anything (or any solution) anywhere.
Not after 80 hours of working on this.

Thank you all.

[ovirt-users] Re: Issue deploying self hosted engine on new install

[Robert Webb]

Just wanted to close this out.

Now that I have solved my NFS issues, I completed a clean install of oVirt node 
on two Dell R410's and ran the self hosted engine wizard on one of them. The 
install went flawless and I now have a working setup.

Thanks for the time and patience from everyone who helped.

For testing, I have set SELinux to permissive on the oVirt host. The NFS server 
is Debian based and does not use SELinux.

So the link to the NFS storage troubleshooting page is where I found that the 
perms needed to be 755.

So in my OpenMediaVault setup under shared folders, I have set the owner as 
vdsm:36  and group as kvm:36. I have set owner as rwx, group as rx, and other 
as rx.

However, when oVirt writes new files, the image file and the .lease file gets 
perm of 660, and the .meta file gets perms of 644.

Like this:

drwxr-xr-x+ 2 vdsm kvm4096 Dec 10 09:03 .
drwxr-xr-x+ 3 vdsm kvm4096 Dec 10 09:02 ..
-rw-rw  1 vdsm kvm 53687091200 Dec 10 09:02 
5a514067-82fb-42f9-b436-f8f93883fe27
-rw-rw  1 vdsm kvm 1048576 Dec 10 09:03 
5a514067-82fb-42f9-b436-f8f93883fe27.lease
-rw-r--r--  1 vdsm kvm 298 Dec 10 09:03 
5a514067-82fb-42f9-b436-f8f93883fe27.meta


So, with all that said, I cleaned everything up and my directory permissions 
look like what Tony posted for his. I have added in his export options to my 
setup and rebooted my host.

I created a new VM from scratch and the files under images now look like this:

drwxr-xr-x+ 2 vdsm kvm4096 Dec 10 09:03 .
drwxr-xr-x+ 3 vdsm kvm4096 Dec 10 09:02 ..
-rw-rw  1 vdsm kvm 53687091200 Dec 10 09:02 
5a514067-82fb-42f9-b436-f8f93883fe27
-rw-rw  1 vdsm kvm 1048576 Dec 10 09:03 
5a514067-82fb-42f9-b436-f8f93883fe27.lease
-rw-r--r--  1 vdsm kvm 298 Dec 10 09:03 
5a514067-82fb-42f9-b436-f8f93883fe27.meta


Still not the 755 as expected, but I am guessing with the addition of the 
"anonuid=36,anongid=36" to the exports, everything is now working as expected. 
The VM will boot and run as expected. There was nothing in the any of the 
documentation which alluded to possibly needed the additional options in the 
NFS export options.

Since I now know what to add to make it work, whether it is right or just a 
workaround, I can now move forward with more testing.

For documentation purposes, here is what my mount looks like on the oVirt host:

nfs_server:/export/Datastore2 on 
/rhev/data-center/mnt/nfs_server:_export_Datastore2 type nfs 
rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nolock,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=nfs_server,mountvers=3,mountport=36103,mountproto=udp,local_lock=all,addr=nfs_server)

Here is what my vdsm user looks like:

id vdsm
uid=36(vdsm) gid=36(kvm) groups=36(kvm),179(sanlock),107(qemu)


Thanks for all the help.

You should not need the '7' for 'other'. Does it work for you with 750?

See also:

https://ovirt.org/develop/troubleshooting-nfs-storage-issues.html

Generally speaking:

Files there are created by vdsm (vdsmd), but are used (when running VMs)
by qemu. So both of them need access.

Good luck,

[ovirt-users] Still having NFS issues. (Permissions)

[Robert Webb]

So I have doubled checked everything I can think of and am still having issues.

I have an NFS Storage Domain attached and I can now create, modify, and remove 
VM's with no issues. The issue I am having is when it is time to power on the 
VM.

The issue is that when oVirt tries to access the image, access is being denied. 
I have double checked the documentation against my setup and it all looks right.

I have the VDSM user and KVM group created with id's of 36. New files are being 
created with permissions of 755, just as the documentation describes.

What I have found out though, is that in order for oVirt to have access to the 
files, the "other" permission has to be a 7. So effectiviely I need to have 
757, rwx, on the files. Is there a user that I am missing from the 
documentation, or a user on oVirt that should be in a group, that isn't?

Someone previously mentioned the sanlock user, but I do not see anything 
special that is required for it.

This is my last hurdle before really being able to dig into oVirt.

[ovirt-users] Re: Issue deploying self hosted engine on new install

[Robert Webb]

Nate,

Thanks for the tip, but the NAS is Debian based.


Is it potentially an SELinux denial?  I seem to recall an SELinux Boolean that 
needs to be set on the nfs server.

I tracked the issue down after giving up on the self hosted install. I

added my hosts.

After adding the hosts and dploying a VM on oVirt, everything deployed 
perfectly, I could never get the VM to start. Digging further, I found that it 
is apparently a NFS permission on my NAS. What is odd is that I can add the 
Storage domain with no issues, I can create a VM, but the VM will never start 
due to a permission issue on the disk image.

On my NAS if I just go into the shared folder permissions and not change 
anything but just tell it to apply configured permissions to all files and 
folders, the newly created VM runs just fine. For some reason when oVirt 
creates new files in storage, it is leaving off the execute for the vdsm user. 
I also notice that for the image and lease files, it also leaves off any 
permisson for "other" . NOt sure why the permissions are not being applied 
correctly. But that is an issue for me to figure out on my NAS, OpenMediaVault.

[ovirt-users] Re: VLANs with one NIC in ovirt

[Robert Webb]

How is your switch port configured?

The switch port, in your case, would have to be set up in trunk mode, for the 
vlan 5 tagging, then also have a native vlan defined, for the untagged 
management packets.

Hi Joseph, I did that but the problem is that I have an ovirtmgmt network by 
default and another network that is a VLAN, VLAN 5 exactly. But VMs that are in 
VLAN 5 cannot go outside. Maybe it could be because the traffic on ovirtmgmt is 
unlabeled and on VLAN 5 it is tagged. Or maybe I have to create some internal 
route so that VLAN 5 packets can exit on ovirtmgmt. I don't know what exactly 
happens and I would like to help me.

[ovirt-users] Issue deploying self hosted engine on new install

[Robert Webb]

Hi all,

I am trying to deploy the self hosted engine via cockpit and it is failing at 
the very end of deployment when it is checking the VM Health. I have done 
multiple clean installs and run this and it fails every time.

I have also tried from the cli via ssh with the same outcome.

After the failure, if I look at the oVirt Machines section of the node, the VM 
is there but will not start.

Anyone else having this issue?

[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.

Good luck,

[ovirt-users] Re: NFS Storage Domain on OpenMediaVault

[Robert Webb]

Thanks for the response.

As it turned out, the issue was on the export where I had to remove 
subtree_check and added no_root_squash and it started working.

Being new to the setup, I am still trying to work through some config issues 
and deciding if I want to continue. The main thing I am looking for is good HA 
and failover capability. Been using Proxmox VE and I like the admin of it, but 
failover still needs work. Simple things like auto migration when rebooting a 
host does not exist and is something I need.

Robert

Does sanlock user has rights on the ./dom_md/ids ?

Check the sanlock.service for issues.
