Thanks for replying, Juan. I was under the impression that the hosted engine would run on an iSCSI data domain, based on http://www.ovirt.org/develop/release-management/features/engine/self-hosted-... and the fact that "hosted-engine --deploy" does give you the option to choose iscsi storage (but only one path, as far as I can tell).
Hosted engine runs fine on iSCSI since oVirt 3.5. It needs a separate target from VM storage, but then that access is managed by the hosted engine HA system. If all the engine hosts are shut down together, it will take a bit after boot for the HA system to converge and try to bring the engine back online (including logging in to the engine iSCSI LUN). You can force this on one host by running "hosted-engine --vm-start". -- Chris Adams <cma@cmadams.net>
