[one-users] disk access via virt-manager

[christopher barry]

Hi Gary,

So, as it turns out, I already had that all set as you describe below.

I changed:
dynamic_ownership=0
to
dynamic_ownership=1

and this allowed me to run the kvm locally as oneadmin in virt-manager.
It's essentially just chown-ing the disk for me automatically now.

hopefully this will help others seeing this behavior.

Regards,
-C
