Hello Michal,
The Live Migration fails. Events does not show any information but just
mentioning migration failed. This happens even when we put the host into
maintenance. VMs do not migrate and host fails to move into maintenance
mode.
Attempted to upgrade the Hosts, but failed, no reasons attached.
I am a bit lost at this stage. Should we check for some more information
in some logs? If yes, where do we find the logs?

Thanks & Regards,

Hello Michal,
Guest tools are working and getting all details about guest vm as needed.
But one thing I didn't understand. What is the relationship between
virtioserial driver and oVirt Guest Service? Without virtio serial
driver, guest services does not start.
Also, how do we install memory baloon driver?
Tomorrow morning, I will post about Live Migration events after I
attempt it.

There should be more details in the events at the bottom of

<div>If they are busy VMs then you may have issues migrating
