vMotion fails with following Error: "problem detected at CPUID level 0×80000001"

Symptoms :
=========
  • Migrating from, for example, esxhost1 to esxhost2, modifies the virtual machine’s configuration to preserve the CPU feature requirements for its guest operating system.
  • Performing a vMotion from one host to another within a cluster fails  
  • The vMotion check fails with this CPU mismatch 
  • Error: Unable to migrate from esxhost365x1 to esxhost365x2: The CPU of the host is incompatible with the CPU feature requirements of the virtual machine; problem detected at CPUID level 0×80000001 register ‘edx’
  • In vCenter Server, you may see an error that indicates that a mismatch has been detected.

Cause :
======
  • The issue can occur on IBM x3650 systems. 
Resolution :
