[Qemu-devel] [PATCH 00/15] block: Overriding the backing file with -drive |

This is the next part of the driver-specific options. Looks like we're getting
closer to pass file descriptors for the whole backing file chain. In fact, I
hope we're now only lacking QMP support before we can actually use it. :-)
This series adds support for the backing.* options namespace, and allows to use
the file.filename option to configure the filename string for non-top-level
BlockDriverStates. In the end you can use things like:
-drive file=test.qcow2,backing.file.filename=/dev/fdset/1,
backing.backing.file.driver=nbd,backing.backing.file.host=localhost
On another note, I'm still not sure whether I should leave all of this work
enabled for 1.5, or if we wouldn't be better off with disabling it for the
release so that we have some additional months before we commit to the
interface. Any opinions?
