I just uploaded some experimental code to the git repository: 

https://git.proxmox.com/?p=qemu-server.git;a=commit;h=30a3378acdd2a6c40998a455c26437888fd98196 

This can completely replace the current code. What do you think? 

(just set exec flag on the file, then you can start it and play around).
