Description of problem:
libvirt-0.10.2-18.el6_4.8.x86_64 breaks both VNC and SPICE console access in RHEV 3.2

Version-Release number of selected component (if applicable):
libvirt-client-0.10.2-18.el6_4.8.x86_64
libvirt-0.10.2-18.el6_4.8.x86_64
libvirt-lock-sanlock-0.10.2-18.el6_4.8.x86_64
libvirt-python-0.10.2-18.el6_4.8.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install RHEV 3.2
2. Upgrade libvirt to 0.10.2-18.el6_4.8.x86_64
3. Restart hypervisors, possibly also management server.

Actual results:
In the webadmin interface I get the error message, "Error while executing action SetVmTicket: Unexpected exception".

Expected results:
Console opens up

Additional info:
Shutting down the VM's, putting the hypervisor into maintenance, running 'yum downgrade libvirt*' to get 0.10.2-18.el6_4.5, setting the host back to active, and restarting the vm's gets things working normally again.

I had to do downgrade the packages and restart ovirt-engine on the management server to get SPICE working again. VNC worked again just from doing the above steps on the hypervisor.
