The problem is that QEMU will find backing file file names inside the images which it will be unable to open. How do you suggest we get around that?
This is the part with allowing libvirt to override the backing file. Of course, this is not something that we can add with five lines of code, it requires -blockdev.
It can be done without blockdev. Have a dictionary that translates filenames, and populate it from the command line (for a bonus, translate a filename to a file descriptor inherited from the caller or passed via the monitor). -- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain.
