to that issue i can still say:
xm migrate works now, since I reinstalled my backup host, happened already 2nd time!
xl migrate, never worked, it goes up to the end, 100%, then an error which says:

This is what bothers me. Any firewall rules or such?
try to first telnet to the peer
telnet <host> 8002
if you can telnet to that port, then please check the target host's xend.log
for any errors.

pasi,
sory for the email before, save/restore works! I mistyped safe instead of
save, been already a long day :-)
Ok, so save/restore works, but live migration doesn't..

Have you configured the relation server & hosts in /etc/xen/xend-config.sxp?
(xend-relocation-server yes)
(xend-relocation-hosts-allow '^localhost$ ^localhost\\.localdomain$')
Check /var/log/xen/ as well for some extra info. Also, this is more suited for the xen-users mailing list :)
