Hi,

I've been having the same problem you've been speaking about, and I was
wondering if there is any continuation... did you find how to live migrate
without soffering the reboot in the new host?

In my case, it seems the migration works ok appart of the reboot. I cannot
migrate back, but I belive it is normal.

Thanks!
