In Xen 3.2.1 the following scenario does not work;

Server A:
Dom0 - 64bit
Hypervisor 64bit

Server B:
Dom0 32bit-PAE
Hypervisor 32bit PAE

With the above setup you can not do a live migration of a domu-32bit-PAE between the server due to apparently from my reading the Dom0's CPU type has to match on both the servers.

With Xen 3.3.0 does now work due to the following:-

  * CPUID feature levelling: allows safe domain migration across
    systems with different CPU models

If anybody could confirm it would save me a lot of messing around with my servers.
