Choose a processor supporting SLAT

The R2 release of Hyper-V added the support for a new feature that reduces the memory required by the hypervisor for each running virtual machine and also provides a performance boost. With that functionality, the processor itself takes over the place keeping of virtual machine memory and how it maps to the memory on the host. By letting the processor perform this operation, the hypervisor uses less memory, and the amount of processor power required is decreased. Again, go out and a tree!

With newer processors from both Intel and AMD, Hyper-V can enable the Second Level Address Translation (SLAT) functionality. SLAT requires a processor that supports either Extended Page Tables (for Intel processors) or Rapid Virtualization Indexing (for AMD processors).
