It's not just about default configs. We need to validate if the
migration formats are truly compatible (qemu-kvm -> QEMU, the other way
around definitely not). For the command line switches, we could provide
a wrapper script that translates them into upstream format or simply
ignores them. That should be harmless to carry upstream.

But I would really stop worrying about the qemu-kvm code base.
