Hi, I've seen a CI failure on qemu-io tests in ovirt-4.2 branch:
http://jenkins.ovirt.org/job/vdsm_standard-check-patch/602/
It fails only in some testing parts, while in others it succeeds:
http://jenkins.ovirt.org/job/vdsm_4.2_check-patch-el7-x86_64/553/

Nir, could you please take a look whether we need to backport your fix
from master and/or fix anything else (such as ensuring the right QEMU
version is used)?

Thanks,
Milan
