Maybe you wouldn't have to move it - Simply set the UML up so that the 
swap file is stored on the other server (have a script which takes out 
the existing swap file, if any, then includes the other one - I figure 
paging to disk all the time over a LAN is bad), suspend it, and it'll 
write the current state to the other box. If you have your rootfs stored 
using COW, you could permantly write the backing file to other machines, 
so you would only need to copy over the spare 'diff' file, which is 
probably going to be fairly minimal. Then just bring the UML up, 
pointing it to the appropriate state file which was written to the other 
server.
