I have a test environment. Three node HCI cluster. CentOS8 build. Gluster as file system with standard cockpit deploy of HCI.
Converted to CentOS Streams which seemed to go fine. Did a yum update and no issues.
Did a reboot.. and now engine will no longer start. So I can no longer start my Virtual machines. I posted as bug https://bugzilla.redhat.com/show_bug.cgi?id=1911910 I posted to CentOS forum https://forums.centos.org/viewtopic.php?f=54&t=76716 but no responses.
Can anyone provide means or next step to root cause and or fix? It would take me days to rebuild the entire solution and I really hate to "reload" as a fix.. but after two weeks... nothing changing... just have to find some means to get cluster back working.
Thanks.

Is their a means to start a VM... when oVirt / engine is offline?

Hi, I would recommend to reach users@ovirt.org mailing list for oVirt related issues.
Converted to CentOS Streams which seemed to go fine. Did a yum update and no issues.
Did a reboot.. and now engine will no longer start. So I can no longer start my Virtual machines. I posted as bug https://bugzilla.redhat.com/show_bug.cgi?id=1911910 I posted to CentOS forum https://forums.centos.org/viewtopic.php?f=54&t=76716 but no responses.
Can anyone provide means or next step to root cause and or fix?
We pushed a fix which is in current nightly but please keep using CentOS Linux for oVirt till it will be officially announced its full compatibility with CentOS Stream. Currently it's a tech preview up to oVirt 4.4.4.
It would take me days to rebuild the entire solution and I really hate to "reload" as a fix.. but after two weeks... nothing changing... just have to find some means to get cluster back working.
Thanks.
