In order to debug, you will need to compare the files provided when you
press the "console" button from both clusters and identify the problem.
Have you compared the firewalld ports on 2 nodes (old and new cluster)
?

Re: VM console does not work with new cluster.

Did you shut down the vm's and start them up on the new cluster? It sounds like they are associated with the default still and that's where virt viewer is looking for them..

Sounds like it, but VMs are running on the same network, with the same IP address. The only firewall involved are on the hosts, and they are both firewalld, and have the same ports and service permitted.

This sounds like firewall issue.

The new ('two') cluster hosts are connected to the same networks as the original systems ('default'). (They have the same assigned IP address.)
Firewalld is reporting the same ports and services enabled on 'default' and 'two' hosts. The VM's are not running firewalls.
Apparently I'm missing something.

how to fix time-drift on el8 hosts?
by Nathanaël Blanchet
Hello,
Engine complains about my fresh el8 ovirt 4.4.3 node host:
"Host hadriacus has time-drift of 3202 seconds while maximum configured
value is 300 seconds."
I tried to fix it with these commands:
sudo chronyc -a makestep
chronyc sources
chronyc tracking
... but the host is still not synchronized.
How should I proceed?

Timeout in "Add HE disks" task
by Jiří Sléžka
Hello,
I am trying to upgrade RHV4.3.10 (standalone) to RHV4.4.3 (HE) in one
step which is probably not supported but in case of our oVirt cluster it
worked well.
I am using hosted-engine --deploy with answer file
hosted-engine --deploy --restore-from-file=backup/backup.tar
--config-append=answer-file_pontus.txt
I can pass until this task
[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Add HE disks]
then ansible fails with a "Timeout exceed while waiting on result state
of the entity."
In the engine I can see that he_virtio_disk is successfuly created and
in OK state but he_sanlock is in LOCKED state. Shared storage domain is FC.
Here is part of ovirt-hosted-engine-setup-ansible-create_target_vm.log
...

"content": "hosted_engine_sanlock",

Do have anybody an idea where could be problem?
Thanks in advance,
