Windows Server 2012 R2 on RHEV 3.3

Greetings!
We have an odd situation involving RHEV 3.3 and Windows Server 2012 R2. We can successfully launch the Windows Setup installer on a bare metal system or Hyper-V instance, but when we try to boot a RHEV 3.3 hosted VM using the same ISO file, the setup installer never launches, and we get an odd reboot loop. Has anyone ever seen this? Does anyone have any suggestions?

Thanks!
