You are welcome, i hope it helps.

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.

Thanks for your response, and apologies for the delay in replying.
I was thinking if it would also be possible to migrate the current
Plan 9 setup that is used with Xen to Qemu.
Thanks.
