osc compute assisted-volume-snapshot

Assisted volume snapshots (os-assisted-volume-snapshots)

Creates and deletes snapshots through an emulator/hypervisor. Only qcow2 file format is supported.

This API is only implemented by the libvirt compute driver.

An internal snapshot that lacks storage such as NFS can use an emulator/hypervisor to add the snapshot feature. This is used to enable snapshot of volumes on backends such as NFS by storing data as qcow2 files on these volumes.

This API is only ever called by Cinder, where it is used to create a snapshot for drivers that extend the remotefs Cinder driver.
