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. Jan -- Siemens AG, Corporate Technology, CT RTC ITP SDP-DE Corporate Competence Center Embedded Linux
