When snapshot handlers of the format driver is not defined, it is
better to call the ones of the protocol driver.

Hi everyone,
Sheepdog is a distributed storage system for KVM/QEMU. It provides

Sheepdog supports advanced volume management features such as snapshot,
cloning, and thin provisioning
, because Sheepdog locks a VM image when it is opened.
To avoid this problem, locking must be delayed until migration has done.
This is also a TODO item.
