[ovirt-users] Hosted engine on Ceph RBD

[Bond, Darryl]

Nir,
I absolutely understand why you would want to use Cinder for oVirt disk management.
My question as only about the hosted engine storage which is a 'special case'. The engine-setup process could have the path to the RBD and secrets file.
At the moment, you need shared storage just for the hosted engine,. Even when it is hosted on gluster it is recommended to be on its own volume.

I agree that this would be nice, but unfortunately working with ceph storage
requires cinder. Engine is managing disks via cinder, and also manage
deployment of ceph secrets on the hosts that need access to the ceph.

For long term we want to support not only ceph but all storage supported
by cinder, leveraging cinder echo system.
