Explanation:

Basic System Administration GuideMigrating Virtual Machines :Migration with VMotion : VMotion Requirements Within the Intel P4 and AMD Opteron processor families, VMware places a restriction between processors that do support the SSE3 instructions and processors that do not support the SSE3 instructions because they are application level instructions that bypass the virtualization layer, and could cause application instability if mismatched after a migration with VMotion. Processor clock speeds and cache sizes, and the number of processorcores may vary, but processors must come from the same vendor class (Intel or AMD) and same processor family (P3, P4, or Intel core) to becompatible for migration with VMotion.
