Allow snapshots of volatile disks in system datastores
Use case
All our VMs OS disks are instantiated as snapshots from an image. We do this so that at termination there is no cleanup needed of any images. When we add additional disks (e.g. empty FS disks), we also add those as volatile.
The problem arises where we are able to create snapshots from the OS disk (which is a snapshotted image) just fine, but not of any volatile data disks that live in the system datastore.
The system datastore itself is the same backend as the image datastore, so it supports all the same features (e.g. Ceph)
Interface Changes
- Support snapshots of volatile (system DS) disks in core
- Support listing and identification of system disks in general (needed in order to snapshot any specific system disk)
- Expose system disk list in system DS view in Sunstone
- Expose disk snapshot feature for volatile disks in VM view
