Windows 2008 R2 Hyper-V on BL460G7 - X5660 (six core)

Hello,

I'm writing a detailed design guide and I wanted to crosscheck all required BIOS Processor paramters which need to be disabled/enabled.

Processor Hyper Treading => Disabled
No-Execute Memory Protection => Enabled
Intel(R) Virtualization Technology => Enabled

Anything else I'm forgetting?

You should keep HyperThreading Enabled.

The virtualization engines today, can handle the hyperthreading features. It should never hurt performance, but optimize whenever available.

Thx for the answer.
So, this is in contradiction to the following whitepaper?

Yes.

MS recommends it being enabled.

In the past we had major issues with hyperthreading and virtualization. Today theres no penalty by turning it on.

Thx.
