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.
