I've seen resolving live migration issues by installing newer versions of
ovirt ga.
Hm, it shouldn’t make any difference whatsoever. Do you have any concrete
data? that would help.
That is some time ago when runnign 4.1. No data unfortunately. Also did not
expect ovirt ga to affect migration, but experience showed me that it did.
The only observation is that it affected only Windows VMs. Linux VMs never
had an issue, regardless of ovirt ga.
You can always try installing either qemu-guest-agent or

It’s 7.3, likely oVirt 4.1. Please upgrade...
