VM deployment failure because Filter NUMATopologyFilter returned 0 hosts
Issue
Trying to deploy pinned VM's return the following error in the nova logs:
Filter NUMATopologyFilter returned 0 hosts
You may also see the following error while investigating a deployment failure with openstack's CLIL
Message: No valid host was found. There are not enough hosts available
This causes deployment of the VM to fail because the scheduler ended its filter pass with no suitable compute host.
