Hi Michal, I've added libvirt logs for relevant VMs on the previous =
Dropbox
share.
I do not see anything wrong. It=E2=80=99s a bit too much data to go =
through, can you pinpoint the time and VM name when you see a failure?
Thanks,
michal

I've already moved to Minimal Downtime and then to Post-copy with
same =
results. VM migrations continue to fail randomly.
