I was thinking if it would also be possible to migrate the current Plan 9 setup that is used with Xen to Qemu. Thanks.

Can i ask, why do you want to migrate from Xen to Qemu? I am triyint to do the opposite, to use Xen only without any part of Qemu. Some time ago i made support of Xen keyboard and framebuffer, and full Plan9 was working in an X session. But since Xen 4.10.x the framebuffer support stoped to work, i don't know why, it seems only VNC is supported now. But Xen framebuffer uses Qemu, so i was anyway going to reimplement the graphic output via DRM. For the moment i can't say when i finish it.

I would like to have Plan9 in Xen with a support of peripherals as much as possible, and without X.
