[Qemu-devel] [PATCH 22/23] gtk: show a window for each graphical QemuConsole

[Gerd Hoffmann <kraxel@redhat.com>]

Multihead support:  For each graphical console we'll create a gtk
window, so with multiple graphics cards installed you get a gtk window
for each.  vte tabs are attached to the console #0 window.
