One thing I found fairly easy to setup for self-migration, was to use 
software RAID-1 (mirroring) to iSCSI targets on the original and 
destination hosts. When its time to migrate, I add the remote iSCSI disk 
to the RAID-1 array, and when that has synced up 100%, I self-migrate 
there. You can either run your iSCSI (or GNBD haven't tried that) 
targets in dom0, or you can run them in separate domUs (in my 
implementation, you will first fire off a bootstrap of a small 
iSCSI-server domain to the remote host, as my dom0 is not allowed to 
include dangerous stuff such as a TPC/IP stack and an iSCSI server).

That gives me live disk-migration using a simple shell-script.
