Subject: [PATCH] virDomainDiskTranslateSourcePool: Translate 'volume' disks in
whole backing chain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Now that we accept full backing chains on input nothing should prevent
users from also using disk type 'VOLUME' for specifying the backing
images.
Do the translation for the whole backing chain.
