Oracle VM: Server with different "CPU Compatibility Group Model Number" does not allow migration (Doc ID 2090672.1)

Last updated on JANUARY 13, 2016

Applies to:

Oracle VM - Version 3.1.1 and later
Linux x86-64

Goal

This issue is common to Cisco Blades,   Can apply to other blade environments.  One can simply remove a blade and insert a new blade.

Issue, if the Blade is a newer CPU type,  OVM manager still has the old "CPU Compatibility Group Model Number" associated with the removed blade. 

With the old "CPU Compatibility Group Model Number" in place,  migrations of VMs will not occur.
