Comment 1 for bug 1592985

See comments here on Patchset 7: https://review.openstack.org/#/c/317741/

With a fresh devstack today (2016-06-20) I was able to successfully create snapshots from nova. I don't know if it was a change in nova / glance, etc or if the steps I took made the difference. As a note, I used Ubuntu 14.04 server image and ensured that it was fully booted before creating a snapshot. I also logged into the image and created a file in tmp. Doing this I was able to test a variety of scenarios for the facet.
