Using NFS for OpenStack (glance,nova) with selinux by Fabian Arrotin

As announced already, I was (between other things) playing with Openstack/RDO and had deployed some small openstack setup in the CentOS Infra. Then I had to look at our existing DevCloud setup.

Sad as one advantage of gluster is that you could (you had to ! ) user libgfapi so that qemu-kvm process could talk directly to gluster through ligbfapi and not accessing VM images over locally mounted gluster volumes (please, don't even try to do that, through fuse).
