I encountered this when trying to deploy hosts which only had a Designate role. It failed on the following:

TASK [map-role : set_fact] ************************************************************************************************************************************************************************************************************************************************************

It would seem the pre-flight checks aren't run for non-hypervisors.

When this is fixed, the deauth role also needs to be adjusted to handle hosts without the hypervisor role.
