There's a flag you can pass to the migration API, VIR_MIGRATE_PERSIST_DEST.

Actually I am already using this flag VIR_MIGRATE_PERSIST_DEST but still VM is not persisting on Destination. Do I need to change something while creating the VM?
That flag might not be implemented to xen. But in that case it should explicitly reject the flag. Please file a bug. But if you need a working solution, you can just do a lookupByName on the remote host after migration, then define that guest to make it persistent. - Cole
