It should be relatively simple to tweak QemuOpts to support:

-drive 'driver=qcow2,
        file.driver=gluster,
        file....'

where all whitespace after comma is ignored, with a nice effect of much
more legibility in long command lines.  I might just submit a patch for
that, regardless of what else we do to get rid of QemuOpts.
