Currently we are passing src_node and des_node uuid when we try to run migrate action. In the watcher-applier log, migration fails with following exception ``` Nova client exception occurred while live migrating instance <uuid>Exception: Compute host <uuid> could not be found ``` Based on57f55190ff/watcher/applier/actions/migration.py (L122)and57f55190ff/watcher/common/nova_helper.py (L322), live_migrate_instance expects destination hostname not uuid. This cr replaces dest_node uuid to hostname. Closes-Bug: #2109309 Change-Id: I3911ff24ea612f69dddae5eab15fabb4891f938d Signed-off-by: Chandan Kumar (raukadah) <chkumar@redhat.com>
