Comment 5 for bug 1692555

My opinion on the matter is that the current approach is too opinionated.

I do have a single host that is both a nova-compute and a cinder-volume host. But the cinder-volume service is not using the LVM driver. So I personally have little concern with ensuring OSA can deploy cinder-volume with the LVM driver.

I view cinder-volume with LVM driver as a lab/test solution. I could be wrong about that, maybe people use it in production. nova-compute attaching to iSCSI cinder volumes, regardless of the volume driver should be a higher priority.

I'd classify this as a security issue too. I've seen compute hosts detect a guest's swap logical volume and attach it. OSA isn't doing anything to prevent that. So this gives a guest the opportunity to write to the host's memory.
