Why did you install rdo-openvswitch? The oVirt project uses
ovirt-openvswitch and it should be pulled in automatically as a dependency.

[ovirt-users] Q: Engione 4.4.10 and New Host on CentOS Stream 9

2022-08-28 Thread Andrei Verovski 

Hi,

I have engine version 4.4.10.7-1.el8, is it possible to set up new node 
host on CentOS Stream 9, or I need to upgrade engine to version 4.5 
first (which is not right now possible because of some quite old nodes) ?


Thanks
Andrei

Note that the thread you refer to is about a snapshot-based mechanism for
backup.
While we still test it (and unfortunately didn't notice the reported issues
on our environments, thus we need more information as Benny pointed out),
we have been putting our efforts on an alternative mechanism that is based
on incremental backup.
This mechanism is supported (since oVirt 4.5.1 I believe) and should
provide you with ways to finalize backups.
It would be great if you can elaborate on what "pending backup operations"
means to see it's covered by that new mechanism we call "Hybrid backup":

How is networking configured on the hypervisors?  Single NIC (or bond) or
multi-homed?
