XEN Live Migration

Now for what is probably the easiest part of the whole process. Now that we know that you have a working iSCSI configuration and a working XEN virtual machine on both clients we are ready to test the live migration process.

With the virtual machine running on one of the clients, (dangermouse in this example) run this command as root on that same machine:

dangermouse:~# xm migrate --live virtual01 buggles

Hopefully after a few seconds the command should return without printing anything. If that is that case then that is probably a very good thing. Check on both clients using xm list to see that the virtual machine has indeed migrated to the second node. If it has, congratulations!
