Yeah... I usually just scp the filesystem image from Host A to Host B,
copy the config file likewise, and start the guest on Host B.

Migration in Xen is a bit different than migration in VMWare...

Another thing I've tried to varying success is to create a guest, the
make a tarball of the guest and it's config, and save that tarball on
a storage server so I can deploy that same guest to multiple machines.
 That's just something I do to ease testing... and it doesn't always
work... but simply copying the guest filesystem from one machine to
another along with its config file works just fine.
