Description of problem:
Unable to start a virtual machine named "power"

Version-Release number of selected component (if applicable):
7.3 public beta

How reproducible:
every time

Steps to Reproduce:
1. virsh start power

Actual results:
SELinux denial

Two curiosities:
1) The file /run/systemd/system/machine-qemu...power.scope has a context of power_unit_file_t rather than systemd_unit_file_t - this was also true in 7.2.
2) In 7.2 the virtual machine started just fine.
3) In 7.3 the virtual machine fails to start.

Expected results:
Virtual machine starts
