The nova-compute agent is reported unavailable by Openstack.

The page refers to widespread unavailability of nova-compute agent across the cluster.

Check the status of nova-compute on a cloudcumin host with:

   cumin C:profile::openstack::base::nova::compute::service 'systemctl is-active nova-compute'

It will show you which hosts have nova-compute unit inactive. Also check for recent puppet changes that might have affected nova-compute operations.

Usually anyone in the WMCS team should be able to help/debug the issue, the main subject matter expert would be Andrew Bogott.
