Processor Compatibility Mod

Overview

Allows live migration across different CPU vewithin same processor family

Configure compatibility on a per-VM basis

Abstracts VM down to the lowest common d(instruction sets available to VM)

Benefits Greater flexibility within clusters

Enables migration across a broader ranger ofhost hardware
