As this is on yet unreleased API this change is possible.
This patch changes devAlias parameter in event callback to
disk target as mgmt application is more likely to know target
(it's required on domain definition) but aliases are generated
by the daemon. So we can say this spares mgmt application at least
one subsequent call of dumpxml on incoming event.
