Interesting. Does live migration not work on ext3 or ext4?

No. You need a shared filesystem. Which pretty much leaves you on either NFS or a clustered filesystem. RH has an example of using NFS - with a strong statement attached that you shouldn't do it that way in real life because the performance is poor.

Trying to mount ext3 or ext4 simultaneously from two machines (on say iSCSI) would just result in filesystem corruption.
