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

[Charles Gruener]

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

gpxe-roms-qemu.noarch            0.9.7-6.12.el6
 @rhel-x86_64-server-6
libvirt.x86_64                   0.10.2-46.el6
@rhel-x86_64-server-6
libvirt-client.x86_64            0.10.2-46.el6
@rhel-x86_64-server-6
libvirt-lock-sanlock.x86_64      0.10.2-46.el6
@rhel-x86_64-server-optional-6
libvirt-python.x86_64            0.10.2-46.el6
@rhel-x86_64-server-6
ovirt-release35.noarch           001-1
@/ovirt-release35
qemu-img-rhev.x86_64             2:0.12.1.2-2.415.el6_5.14 @ovirt-3.5

qemu-kvm-rhev.x86_64             2:0.12.1.2-2.415.el6_5.14 @ovirt-3.5

qemu-kvm-rhev-tools.x86_64       2:0.12.1.2-2.415.el6_5.14 @ovirt-3.5

vdsm.x86_64                      4.16.7-1.gitdb83943.el6   @ovirt-3.5

vdsm-cli.noarch                  4.16.7-1.gitdb83943.el6   @ovirt-3.5

vdsm-jsonrpc.noarch              4.16.7-1.gitdb83943.el6   @ovirt-3.5

vdsm-python.noarch               4.16.7-1.gitdb83943.el6   @ovirt-3.5

vdsm-python-zombiereaper.noarch  4.16.7-1.gitdb83943.el6   @ovirt-3.5

vdsm-xmlrpc.noarch               4.16.7-1.gitdb83943.el6   @ovirt-3.5

vdsm-yajsonrpc.noarch            4.16.7-1.gitdb83943.el6   @ovirt-3.5

virt-what.x86_64                 1.11-1.2.el6
 @anaconda-RedHatEnterpriseLinux-201301301459.x86_64/6.4

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.
