Xen users - Jan 2010 - Live migration between host with different CPU speed

Does Xen support live migration between host that has different CPU
speed, but with the same CPU architecture?
(eg: one host is running Intel Nehalem E5520 at 2.26 Ghz , while the
other host is running Intel Nehalem E5540 at 2.53 Ghz)

If so, what will happen after the VM has been migrated to the host
with lower or faster CPU speed?

Thanks

Hello,

It works even with different CPU, I succeed to migrate some domains (one
XP and one Debian 5) between :
An Opensuse (11.2) system with XEN 3.4.2 fitted with
model name	: AMD Athlon(tm) 64 X2 Dual Core Processor 4400+
and
on a Debian unstable with a Xen from the dev tree (3.4.3) fitted with
model name	: AMD Phenom(tm) II X4 905e Processor

The disk images where on a small NAS accessed by NFS, the network goes
through a 1Gb DLINK switch. Migration was done with # 30 seconds
"dead"
on the virtual machine.

Regards

JPP
