It was a hell like experience upgrading 4.4.7 to 4.4.10.

I will post an instruction in my blog.

[ovirt-users] Incorrect Max CPU's per VM in libvirt if cluster compatibility 4.6 or 4.7

2022-07-19 Thread David Sekne
Hello,

I recently upgraded our cluster from 4.3 to 4.5 (4.5.1.3-1.el8), I raised the 
cluster compatibility afterwards to 4.7 as well. I noticed that the CPU hot 
plugging does not work above 16 CPU's if cluster compatibility is set to 4.6 or 
4.7. 

Error I get is: 
Failed to hot set number of CPUS to VM testVM-3. Underlying error message: 
invalid argument: requested vcpus is greater than max allowable vcpus for the 
live domain: 32 > 16

Issue here I believe is that the MaxNumOfVmSockets values set on the engine per 
cluster version is not correctly set on libvirt when VM is started.

My values on the engine:
MaxNumOfVmSockets: 32 version: 4.2
MaxNumOfVmSockets: 32 version: 4.3
MaxNumOfVmSockets: 32 version: 4.4
MaxNumOfVmSockets: 32 version: 4.5
MaxNumOfVmSockets: 64 version: 4.6
MaxNumOfVmSockets: 1 version: 4.7

Values on libvirt for VM's for all cluster compatibility versions:

4.3
32

4.4
32

4.5
32

4.6
16

4.7
16

Is anyone else experiencing this issue (possible BUG)?

Regards,
David

[ovirt-users] Re: Grafana login

2022-07-19 Thread Artur Socha
Hi everyone,
I think what you found here is the bug. Partially it was fixed in the
mentioned BZs but later we realized it still exists under some
circumstances.
I have posted GitHub PR [1] addressing it and it has already been merged.
This fix is expected to be released as part of oVirt Engine 4.5.2.
After that, it will be possible to fully use SSO ie. login with the same
username to grafana and oVirt. The root cause for this bug was a different
'admin' email being used in grafana and oVirt.
Until then, I think it should be possible to login grafana/monitoring
portal:
1) when no keycloak enabled:  use 'admin' and don't use  'oVirt SSO' on
grafana login page
2) when keycloak enabled: use 'admin'  and don't choose  'oVirt SSO' on
grafana login page
3) when keycloak enabled: user 'admin@ovirt' via 'oVirt SSO' on grafana
login page, or login first to oVirt  and then go to grafana (Monitoring
Panel). Last option should not ask you for credentials again as the SSO is
supposed to work.

thanks,
Artur

If not, try to 'reinstall' (UI, Hosts, Installation, Reinstall) the 
host. During the setup, it should give you to update if the host can run 
the HE and it should allow you to select the checkmark for Gluster.


well, in my oVirt install there is no way to setup glusterfs services 
during host reinstall. There are only choices to configure firewall, 
activate host after install, reboot host after install and 
deploy/undeploy hosted engine...


I think that gluster related stuff is installed automatically as it is 
configured on cluster level (where in my case are gluster services 
disabled).


Let's work with a single node before being so drastic and outage-ing a 
cluster.

If you export as OVA from oVirt you will get a tar file, so that if you
untar it you will also find the disks' files.

It's most likely a feature.  Starting with 4.6, the maximum number of
vCPUs is limited because it consumes resources even if the CPUs are not
plugged in.  Adjusting sockets/cores/threads configuration of the VM to
put more than one vCPU on a socket or changing MaxNumOfCpusCoefficient
config value should help in your case.

Milan

[ovirt-users] Re: gluster service on the cluster is unchecked on hci cluster

2022-07-19 Thread Strahil Nikolov via Users
Then, just ensure that the glusterd.service is enabled on all hosts and leave 
it as it is.
If it worries you, you will have to move one of the hosts in another cluster 
(probably a new one) and slowly migrate the VMs from the old to the new 
one.Yet, if you use only 3 hosts that can put your VMs in risk (new cluster 
having a single host could lead to downtimes).
To be honest, I wouldn't change DB if it's a productive cluster. If you decide 
to go that one -> make an engine backup before that.

4.6.

MaxNumOfVmSockets: 32 version: 4.4
