By default, virt-manager (and likely other libvirt-based apps) sets the VIR_MIGRATE_PERSIST_DEST flag when invoking the migrate API, which fails in a Xen setup since the libxl driver does not support the flag. Persisting a domain is a trivial task in the grand scheme of migration, so be nice to libvirt apps and add support for VIR_MIGRATE_PERSIST_DEST in the libxl driver.
