The domain's memory image is transferred. Virtual disks are not migrated (are
you using a SAN, NAS, or similar?), and neither are config files.
The domain's configuration is migrated when the domain moves, but it's held in
memory - it's not stored on the disk. I believe the state will persist as
long as that domain is running, and that server is up.
