有關 VM Host & CPU Virtualization

My Host Server : IBM X306m
Hardware : Pentium D 930 (with VT-x, x64), 8Gb Ram......,

I want to build a XenServer v6.x, but Mainboard BIOS (Updated) no setting to enable virtualization,

Question
- Can I install windows VM in Xen?
- If not, can i install a Virtualization Extended Page file in Xen? how to do?
- Or just be able to install unix/linux base system in vm ???

&

- I ask what VM Server can run it without intel-VT, VT-x or AMD-V ?

Thx. All Brother !!!
