Can you please elaborate on this?
Which package and version of qemu were you running?
We recommend to use the -ev variant (e.g. qemu-kvm-ev).

The -ev variants provide in turn the *rhel* machine types
(qemu -machine ?), and they have much better
compatibility guarantees and an upgrade path.

If you run the pc-* machines, you can easily run into troubles like this.

Good point, but this should be true for rhel* machine types, and I didn't expect
you had pc-* machine in the first place!
Could you please share the package list and versions? Qemu, libvirt, vdsm, ovirt-engine.

Please be prepared to file a oVirt bug, on Engine, because Vdsm is just the humble
servant here, doing exactly what Engine orders.
