Just spitballing here: 14.04 only? Tried 16.04, or any other OS for
that matter? For now, it sounds more guest related rather than oVirt.
/K
I tried a vanilla centos-7.1 as well and the same happens. I'm of the
same opinion that this is more a guest related issue, it's just I'd like
to find out why this only happens with QXL and not with CIRRUS.
Thanks.
