Probably rsync, but scp, rcp, ftp, sftp or any other "copy" tool of your
choice will work.  I'd avoid CIFS.

Treat each VM just like a regular machine. If you've setup a VM-only
switch, using that instead of the public IP would probably be faster,
but if the VM virtual-disks are physically on the same HDD, that will be
the limiting factor.

You could setup NFS between the systems or use iSCSI between them too,
if you like. Probably overkill when rsync is so much easier.
