Thread-topic: [Xen-users] Live migration?
User-agent: Microsoft-Entourage/

I was starting to feel a bit alone ;) But thanks anyway.
Our NFS uses only UDP, and as I wrote, our domU's with "small" amounts of
memory works like a charm. It is only the big ones that are troublesome.

I would really like to have Live Migration working. But no such luck so far

What about the memory requirement I noticed in the log?
Does anybody know if it is for the dom0? or is it because the machine needs
free RAM to do Live Migration?
