I and my team want to contribute the software which automatically migrates XEN 
virtual machines between 2 systems based on their CPU time. The software is 
written in Python. Download the RPM package from 
http://sourceforge.net/projects/profugus
Full documentation for the software is not available it''s pending for 
submittion on sourceforge, but the software has a manpage and here are steps 
to configure the software:
1. You should have XEN configured for migration and have RSA key for 
implementing ssh to the remote machine.
2. Install the RPM package (master host):
rpm -i profugus-0.1.-1.i586.rpm
3.Edit the /etc/profugus.conf:
Remote  {remote host}
Instead of {remote host} put the real name or IP address of the remote host
4.Run profugus first time
       profugus -f
This command will copy your RSA public key to the remote machine
5.Starting the service
service profugus start
Questions, comments, suggestions are welcome
Thanks,
