[Qemu-devel] [PATCH] Keyboard/Mouse Console for vfio with active function x-vga ans -vga none

[qemu Mailinglist]

there are many discus about using keyboard and mouse with VGA passthru,
so I add a graphic_console to vfio.c, like puv3.c.
I test it with SDL and VNC Access, the Keyboard works, the mouse work
good without absolute version like "-usbdevice mouse".
Default it boot with "QEMU PS/2 Mouse", but this is changing to "vmmouse
(absolute)" at boot time of gast system.

I hope someone else can test.
