hi,

I have 2 servers running xen 3.2 on ubuntu 8.0.4.1 (64-bit) installed from the repositories (2.6.24-22-xen) with Intel-Quadcore CPU's. The setup is based on http://www.asplund.nu/xencluster/xen-cluster-howto.html. I can start the domU (ubuntu 8.0.4.1 (64-bit)) on each server without problems. But when I start the live-migration with xm migrate dummy xen2 --live the migration hangs.

Can anyone give me a hint?
