Rename the below file to pingpong.py

Replace the hosts entries with two ips of xen dom0 hosts.

Create a dom0 on one of the hosts.

Run the program on both hosts, by typing "python pingpong.py" from
the command line.

It will start migrating them back and forth in a game of ping pong. ☺

Only a small mutation to the code would randomly pick from hosts to
migrate to if there were more than two dom0’s.
