Thanks for the ground work!

Attached you can find a patch implementing the same flags for Xen:

 * src/xen/xen_driver.c: Add support for VIR_MIGRATE_PERSIST_DEST flag
 * src/xen/xend_internal.c: Add support for VIR_MIGRATE_UNDEFINE_SOURCE flag

I'm not totaly sure if there are better ways to handle all the error
cases. The current solution seemed to be a same one for me.

Ciao
