Kevin Wolf b998875dcf block: Fix snapshot=on for protocol parsed from filename ... Since commit 9fd3171a, BDRV_O_SNAPSHOT uses an option QDict to specify the originally requested image as the backing file of the newly created temporary snapshot. This means that the filename is stored in "file.filename", which is an option that is not parsed for protocol names. Therefore things like -drive file=nbd:localhost:10809 were broken because it looked for a local file with the literal name 'nbd:localhost:10809'. This patch changes the way BDRV_O_SNAPSHOT works once again. We now open the originally requested image as normal, and then do a similar operation as for live snapshots to put the temporary snapshot on top. This way, both driver specific options and parsed filenames work. As a nice side effect, this results in code movement to factor bdrv_append_temp_snapshot() out. This is a good preparation for moving its call to drive_init() and friends eventually.
