I used to build my own debian xen packages some years ago (at the time where xen 3 was released) and I always had the qemu stuff included and fully working.

Bastian start to take over the packaging part after that and changed a lot in the way the packages gets created. I think, that a lot of the changes he made, was useful for getting xen to comply to the debian policies and the debian way of doing things. But on the other hand he removed for example the qemu stuff.

Don't get me wrong... I am very happy that Bastian took care of all this for years now... It just that he changed so much, that it isn't easy to understand every peace of the packaging logic anymore. I wouldn't be able to take the debian xen package source and just add the qmeu part again. Or at least it would take me a lot of work...

I also would like to have a solution for this problem, because there will be xen systems that I have to setup in the future and these systems might need the qemu-dm support.

Maybe Bastian can explain why he removed the qemu stuff and if there is a chance, that he will include it again. I haven't said a word about this in the last years, but I think it is a shame to not have the qemu-dm stuff available. It kills 50% of the xen features. Paravirtualisation is nice, but only 50% of the magic xen can do. The other 50% need the qemu stuff.
