This is another server which I have also problems with. I cannot select SandyBridge as the cpu type.
Still oVirt 3.1 in Fedora 17.

* Tecnology : Sandy Bridge E
* CPU : Intel Xeon E5-1620
* Cores / Threads : 4 / 8
* Frecuency : 3.6GHz / 3.8GHz Turbo Boost

#cpuinfo:
  Intel(R) Xeon(R) CPU E5-1620 0 @ 3.60GHz
