Hello Ali Shah, we are running VMs using Opennebula with ceph as the backend. So far with varying results: From time to time VMs are freezing, probably panic'ing when the load is too high on the ceph storage due to rebalance work. We are experimenting with --osd-max-backfills 1, but it hasn't solved the problem completly. Cheers, Nico Zeeshan Ali Shah [Tue, Dec 23, 2014 at 09:12:25AM +0100]: > Has any one tried running instances over ceph i.e using ceph as backend for > vm storage .
