Make use of XenServer Storage Manager for NFS
nova-volume was able to use XenAPI storage manager. We need to add this back, with the knowledge one SR can only be attached to one Pool (usually one host).
This blueprint looks at adding support for the NFS SR.

Whiteboard
It was briefly discussed at the summit, along side this related work:
https:/
NFS support is chosen due to the large numbers of high performance NFS appliances.
Initial prototyping means we are not doing snapshots in the initial work, this is deferred, probably till H release. This is because cinder must talk back to the hypervisor to take the snapshot, similar to local snapshots.
We will implement:
- create
- delete
- (attach/detach)
Possibly deferred steps:
- create from glance image
- upload volume to swift
