The volume snapshot location depends on the underlying storage. Ceph primary storage is an
example where the Ceph snapshot feature is utilized, keeping snaps on primary storage.
I believe Solidfire may also offer a similar functionality, but probably best to us them directly
on that front.

The new VM based snapshot on KVM requires QCOW2 images due to the memory snapshot requirement
(hence NFS), but it does keep them on primary storage.

Great to hear we are finally getting to the bottom of one of the most annoying things still
present in ACS when it comes to KVM hypervisors! I can't wait to try it out ))). The last
remaining thing to do is to have the ability to keep the volume snapshots on the primary storage
and use the storage's snapshotting capabilities. I think there is work in progress here as
well )))
