Hyper-V: Nova assisted volume snapshot

Registered by Alessandro Pilotti on 2016-11-27

Cinder backends which make use of remote file systems to store volumes as virtual disk images cannot perform snapshot related operations while the volume is attached.

For this reason, the concept of nova assisted snapshots was introduced. It is already supported by the libvirt driver.

This blueprint proposes using a similar workflow for the Hyper-V driver in case of SMB based volume backends.
