Here's what's installed on one of my hypervisors:

I noticed the machines do not have the qemu-kvm package installed, only qemu-kvm-rhev.  What's the difference in those two packages?  When I try to manually install qemu-kvm, it won't and lets me know that:

"Package 2:qemu-kvm-0.12.1.2-2.445.el6.x86_64 is obsoleted by 2:qemu-kvm-rhev-0.12.1.2-2.415.el6_5.14.x86_64 which is already installed"

I've also noticed that I can't live snapshot machines because it says my underlying qemu doesn't support it and thought that might be a related issue.

The machines have Intel(R) Xeon(R) CPU E5-2670 CPUs, if it makes any difference.

Subject: Re: [ovirt-users] oVirt 3.5 on RHEL 6.6 hyperv enabled breaks        Windows VMs

The three Windows VMs I tried were Windows 7, Windows 8.1, and Windows Server 2012 R2.  All experienced the stop error.

This is quite interesting because the hv_relaxed thing was supposed to _improve_ stability for windows 7 onwards.
I was expecting troubles with older windows (XP), not with newer ones.

Can you share what is running on your hypervisors? versions of libvirt and qemu.
Moreover, qemu and libvirt logs would help.

Thanks,
