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
