Hello all After upgrading one node from 4.5.4 to 4.5.5 the migration fails on some of the VMs. I believe the error is with qemu-kvm according to the logs below. Downgrading the packages seems not to be possible with oVirt Node, the only solution so far was rebooting back to 4.5.4 (thanks to imgbase). I also think it is related to https://lists.ovirt.org/archives/list/users@ovirt.org/thread/GGMEGFI4OGZ5QRI..., but that thread is already several months old. Has someone had the same experience and found a solution?
