Hello All,
on ocata when I  poweroff a node with active instance , doing a nova
host-evacuate works  fine
and instances are restartd on an active node.
On queens it does non evacuate instances but nova-api reports for each
instance the following:

2019-07-11 10:19:54.745 13811 INFO nova.api.openstack.wsgi
[req-daad0a7d-87ce-41bf-b096-a70fc306db5c 0c7a2d6006614fe2b3e81e47377dd2a9
c26f8d35f85547c4add392a221af1aab - default default] HTTP exception thrown:
Cannot 'evacuate' instance e8485a5e-3623-4184-bcce-cafd56fa60b3 while it is
in task_state powering-off

So it poweroff all instance on the failed node but does not start them on
active nodes

What is changed ?
