Bug description:
Description
===========
When an instance encounters a HypervisorUnavailable error, the non-admin user gets the info of the compute host fqdn in the error message.
Steps to reproduce
==================
1. Spin up an instance with non-admin user credentials
2. To reproduce the error, stop the libvirtd service on the compute host containing instance
3. Delete the instance
4. Deletion fails providing HypervisorUnavailable error
Expected result
===============
Error does not show compute host fqdn to a non-admin user
Actual result
=============
#spin up an instance
