I've been using Citrx Xenserver for awhile on a few machines that don't support Hardware Virtualization as a test for various small servers.

I recently have been experimenting with moving the PV Vms between machines but Xenserver gives me errors that roughly say I need to have homogenous hardware for this to work.

Because of this I haven't been able to setup XenMotion or any of the nice features that come with server pooling in Xenserver.

I'm considering moving away from XenServer, however I can't seem to find a Hypervisor that explicitly supports non-homogenous clusters.

On a side note, we do have a few idenitally configured Dell 1950s that haven't had any VM solution setup on yet, so if we can find a solution that can allow us to move PVs to those as well that would be great. Non free solutions are OK as well.

What hypervisor will allow this? Thanks!
