libvirt users - Apr 2018 - Permissions and ownership on /dev/kvm keep reverting after starting a vm

Hey guys,

/dev/kvm permissions and ownership keeps reverting after starting a vm.

The ownership and permissions keep going back to
crw-rw—— root root ....

After starting a vm.  I have to revert the perms and ownership to:

crw-crw-crw root kvm ....

To start any vm but it goes back to the first set of permissions as soon 
as I start another vm.  Wondering what could be doing this?

Cheers,
Tom
