Description Daniel Rowe 2016-08-24 09:23:53 UTC 
Description of problem:

Recent update have broken VMs from running.

Looks like maybe a systemd update caused this issue.

Tested on a machine without the systemd update 229-13.fc24 and it works as soon as I update it is broken.

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

Up to date

How reproducible:

Everytime

Steps to Reproduce:
1. Via Virt Manager start a KVM libvirt VM
2. Fails with a error 
3. Try with virtsh
4. Fails

Actual results:

virsh # create /etc/libvirt/qemu/centos7.0.xml 
error: Failed to create domain from /etc/libvirt/qemu/centos7.0.xml
error: SELinux policy denies access.


Expected results:

VM starts
