Re: Plan 9 won't boot on Xen 8.0

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.
