CPU support than can make VM run faster

Hyper –V V2 when is included in WS 2008 R2 uses SLAT (or EPT), it makes VMs run faster.

But I don’t know what type of Intel CPUs who can support this. I guess that EPT is included in the VT-x for support of CPUs.

Can anyone give their opinions about this matter?

In case you need to make the virtual machine run faster by using the CPU specifications, then you will need to observe the details below:

For the CPU speed to increase, you will also need to increase the speed of the processor. The speed will be much faster when you are using a dual, and even more with a quad core, but that means that you will have to spend a little bit more on them so as to get a fast CPU for your computer.

You should note that some of the latest processors will have the virtualization capabilities built in them, but for some of them, the features can only be properly utilized when the new Windows Virtualization, which is called the "Viridian" has been incorporated in them. Once the CPU speed is faster, then your computer will have the better performance and thus handle the extra load of running many VMs at the same time.

“SLAT” stands for “Second Level Address Translation.” It is a hardware-assisted virtualization technology introduced in both Intel and AMD processors which allows you to avoid the overhead associated with software-managed shadow page tables. Other term for SLAT is “nested paging.” Though Intel and AMD offer this feature in their processors, they have different names.

For Intel, their version of the technology is called “EPT” or “Extended Page Tables.” For AMD, they call their version “RVI” or “Rapid Virtualization Indexing.” With Intel, they introduced EPT in their processors that were built on the Nehalem architecture found in several Intel Core i3, i5, and i7 processors while AMD introduced RVI in their third generation of Opteron processors codenamed “Barcelona.”

Hyper-V uses this technology to perform more VM memory management functions and lessen the overhead of translating guest physical addresses to real physical addresses. With this method, the Hypervisor CPU time is decreased significantly and more memory is saved for every virtual machine.
