I'm with Igor on this one. I'm all for QEMU going the extra
mile to
help libvirt, simply because that helps a very large fraction of our
users. I'm now asking libvirt to extend the courtesy back to QEMU.
Please sit down and think earnestly about how to best soften the
compatibility promise you made so you can cope with changes we feel QEMU
has to make.
The compatibility promise of libvirt can in this case go only as far as
qemu is going to allow us. Obviously qemu dropping that option would not
be nice unless libvirt has a contingency plan, but once it's gone we
can't do much more. Libvirt needs to adapt as well so that we do our job
of shielding users from inconsistencies of configuration.

point.
