[Openstack] Wasted Compute node disk space

2013-01-08 Thread Greg Chavez
We are in the process of replacing our Diablo KVM infrastructure with Folsom. Up until now, our virts have been using the local Compute node's disk space for their images which, obviously, defeats much of the purpose of a virtualizing. We are ready to implement an iSCSI SAN, but we're a bit
