two different ways:
first: you have the guest installed into a disc or file, which has
partitions inside (root and swap), so that it only necessary to share
the disk/file over the network.
If the root (/) from the guest in a file, or disc without partitions,
than you have to make sure, that the SWAP file is available on the same
path. You can't create just a new SWAP, cause you don't know if
something was swapped out. First you have to do a swapoff and remove the
disc inside the guest, and after the migration add the disc again and do
a swapon.
the better way is to you the swap file on NFS, or use ISCSI.
