[rdo-list] Recent blog posts you may have missed



There's been a few recent blog posts from across the RDO community that
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).

* Nested quota models by Tim Bell

but the subsequent discussions have also led to further review.
