you may have missed in recent weeks. Here's some of the highlights:


* 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. This setup was
based on Opennebula running on CentOS 6, and also using Gluster as
backend for the VM store. That's when I found out that Gluster isn't a
valid option anymore : Gluster is was deprecated and was now even
removed from Cinder. 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).

but the subsequent discussions have also led to further review.
