There are limitations.  If you are migrating a domU from Host A to Host B,
Host B must support all hardware caps that the domU was aware of on Host A.
There was (is?) some discussion of developing a filtering scheme to provide
the lowest common denominator of capabilities to domU's in a network of
Hosts, but I'm not sure if that got off the ground.  The other manner to
support migration to differing hosts us to define an architecture in your
domU that results in only the capabilities available on all Hosts being

Subject: [Xen-users] Migration of XEN instance on different hardware

Hi all,

I couldn't find any documentation on the restrictions for live migrating,
so I suppose it will be possible to move one instance from any hypervisor
OS to any other? What I can't believe is that there are no restrictions on
the architectures of the hypervisors. Help is very much appreciated.
