VM deployment failure because Filter NUMATopologyFilter returned 0 hosts

Solution In Progress - Updated -


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.
