[Xen-devel] Live migration of DomU created by Xen-API.

Hi, cant signup to the list so please send all replys to me in person
also please.

When i create a DomU using the Xen-API everything works fine except for
migrating the DomU from a machine to another.
The hosts are 2 identical DL320s so they shouldnt be the problem. And if
i create a domU using xm commands it all works fine too.

This is the error i get. If anyone can give me a headsup please do.
