Host fails to activate
by David Johnson
Good afternoon all,
Ovirt version: 4.14.4.10.7-1.el8
Centos version: Linux version 4.18.0-365.el8.x86_64 (
mockbuild(a)kbuilder.bsys.centos.org) (gcc version 8.5.0 20210514 (Red Hat
8.5.0-10) (GCC)) #1 SMP Thu Feb 10 16:11:23 UTC 2022
Background:
We had a mother board fail in our storage device. I was able to migrate the
storage domain to the backup device before it failed completely, and have
been running on the backup device for several weeks while we purchased a
replacement main storage.
Today I shut everything down cleanly, replaced the main storage, and
restarted the cluster. We did disconnect and reconnect the network on all
of the devices as we shuffled equipment in the rack.
One of the hosts in the cluster refuses to come back up.I am able to
connect to the host via putty.

oVirt SSH rate limit and disable SSH passwd auth
by tasnadi.peter＠kifu.gov.hu
Hello,
1.
Is it possible to disable ssh root password authentication in a working oVirt cluster without any problems? (host and ovirt-engine)
/etc/ssh/sshd_config
PasswordAuthentication no
The SSH public authentication key is set on the host.
2.
I tried setting ssh rate limit using firewall-cmd but it doesn't work for some reason. I can log in more than once.
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" priority="-1" service name=ssh limit value=3/m accept'
There is best practice for this?
Thanks

VmMediatedDevices help for vGPU in overt 4.5
by Don Dupuis
Hello
I am looking for an example on how to use the new VmMediatedDevices service
to add an Nvidia vGPU in ovirt to guest vms. I had it working just fine in
oVirt 4.4 when using the custom_properties method. Just need to understand
the new method/way of doing it correctly using the python3-ovirt-engine-sdk.
Thanks

Re: list-view instead of tiled-view in oVirt VM Portal?
by Frank Coons
Please note that (a) there are people that use more than 20 VM's that do
not need admin access, and (b) some people do not LIKE looking at big gaudy
buttons, even if there are only 15 of them.
I put in an RFE to bring back the list view YEARS ago and was basically
told that "we know what you want better than you do." I am willing to bet
that many more people want the list view than you realize, but you don't
seem to be willing to listen.
Disgruntled.

Re: Self-hosted engine failing liveliness check
by McNamara, Bradley
When a run "hosted-engine --check-liveliness" it returns "Hosted Engine is not up!" When I run this command and can see it hitting the httpd server, with success, in the httpd logs. Accessing the URL returns this: "DB Up!Welcome to Health Status!".

Subject: [ovirt-users] Self-hosted engine failing liveliness check
CAUTION: External Email
Hello, and thank you all for your help.
I'm running Oracle's rebranded oVirt 4.3.10. All has been good until I patched my self-hosted engine. I ran through the normal process: backup, global maintenance mode, update the oVirt packages, run engine-setup, etc. All completed normally without issues. I rebooted the self-hosted engine VM, and now it constantly fails liveliness checks and the HA agent reboots it every five minutes, or so. I put it in back in global maintenance so the HA agent would not reboot it. The VM is up and works correctly. I can do everything normally.
From what I can tell the HA agent liveliness check is just a http get to the web portal. I can see that happening with success. What is the lilveliness check actually doing? All services on the VM are up and running without issue. Where can I look to figure this out?
Here is the output of hosted-engine --vm-status:

I think that if you list the devices in this filter:
ls -lh /dev/disk/by-id/lvm-pv-uuid-Nn7tZl-TFdY-BujO-VZG5-EaGW-5YFd-Lo5pwa \
/dev/disk/by-id/lvm-pv-uuid-Wcbxnx-2RhC-s1Re-s148-nLj9-Tr3f-jj4VvE
\
/dev/disk/by-id/lvm-pv-uuid-lX51wm-H7V4-3CTn-qYob-Rkpx-Tptd-t94jNL
You will see that these are the devices used by these vgs:

If you run "vdsm-tool config-lvm-filter" and confirm with "yes", I
think all the vgs
will be imported properly into lvm devices file.
I don't think it will solve the storage issues you have since Feb
2022, but at least
you will have a standard configuration and the next upgrade will not revert your
local settings.

This is not very efficient - this copy the entire vm at the point of
time of the snapshot
and then copy it again to the export domain.
If you use a backup application supporting the incremental backup API,
the first full backup
will copy the entire vm once, but later incremental backup will copy
only the changes
since the last backup.

The problem is that your Gluster storage is not healthy, and reading
and writing to it times out.
Please keep users(a)ovirt.org CC when you reply. Gluster storage is very
popular in this mailing list
and you may get useful help from other users.

Self-hosted engine failing liveliness check
by McNamara, Bradley
Hello, and thank you all for your help.
I'm running Oracle's rebranded oVirt 4.3.10. All has been good until I patched my self-hosted engine. I ran through the normal process: backup, global maintenance mode, update the oVirt packages, run engine-setup, etc. All completed normally without issues. I rebooted the self-hosted engine VM, and now it constantly fails liveliness checks and the HA agent reboots it every five minutes, or so. I put it in back in global maintenance so the HA agent would not reboot it. The VM is up and works correctly. I can do everything normally.
From what I can tell the HA agent liveliness check is just a http get to the web portal. I can see that happening with success. What is the lilveliness check actually doing? All services on the VM are up and running without issue. Where can I look to figure this out?
Here is the output of hosted-engine --vm-status:

How to run virt-sysprep / How to troubleshoot template creation failure
by jeremy_tourville＠hotmail.com
When attempting to create a template the process fails. It has been suggested to run virt-sysprep manually and see why it it failed. Specifically, I have an Ubuntu 20.04 machine that doesn't boot properly even if the the template process does finish without error. I have tried creating the template several times as a test. about 80% of the time the template creation fails outright for qemu errors. The other 20% "appear" to work but the system boots to a grub emergency prompt
Can someone clarify the process?
I know you can run the command: virt-sysprep -d <name_of_vm>
1. Where do you run it from? The hypervisor host or the management engine?
2. What account do you need to use? What is the authentication username and password?
I also think I read somewhere that you should refrain from using root. Anything else to know?
Anything else to try regarding the grub prompt?
Thanks.
