Nova compute service is down

Solution Verified - Updated -

Issue

  • Cannot evacuate because nova compute service is down. We expect the nova-compute service to be running in order to evacuate the VMs to another compute.

  • We're using High Availability for compute instances (Instance HA)

  • Service appears down for that compute:
