[Bug 2076089] [NEW] admin cannot force instance launch on disabled host
Public bug reported:
Description
===========
I have a set of disabled nova compute services, with nova compute service up and running, and I would like to force instance creation, as admin, on a disabled conpute node for testing purposes.
I added the option --availability-zone nova:$HOST to the openstack
server create command, however it fails with "no valid host found" even
if it should have skipped placement filters.
Steps to reproduce
==================
* openstack compute service list --service nova-compute

Expected result
===============
Launch process should have skipped placement filters and instance should have been launched on requested hypervisor
