I don't know of any guide besides the official install docs from grizzly/havana, but I'm running openstack grizzly on top of rbd storage using glance & cinder and it makes (almost) no use of /var/lib/nova/instances. Live migrations also work. The only files there should be "config.xml" and "console" - otherwise, live-migrations won't work OR the path should be a mounted shared storage (NFS, GlusterFS etc).
Nova-compute stores "disk*" files under that path in the following cases: - when one starts an instance only by using "--image <image id>" argument to nova-boot, without a pre-created cinder volume and without the "--block-device-mapping" argument - when one uses a "config disk" for bootstrapping instances - when one configures a "swap" disk in the flavor used to start the instance On Nov 2, 2013, at 2:32 AM, Gaylord Holder <[email protected]> wrote: > http://www.sebastien-han.fr/blog/2013/06/03/ceph-integration-in-openstack-grizzly-update-and-roadmap-for-havana/ > > suggests it is possible to run openstack instances (not only images) off of > RBDs in grizzly and havana (which I'm running), and to use RBDs in lieu of a > shared file system. > > I've followed > > http://ceph.com/docs/next/rbd/libvirt/ > > but I can only get boot-from-volume to work.
