Ian, Daniel

 my patch is almost like Daniel's one.  Thank you for pointing to it.

And there's one absent thing in Daniel's commit (4f6fee3a456e). To 
complete the gfx passthrough issue for xl we should pass this option to 
qemu-dm, like this :
+        if (info->gfx_passthru) {
+            flexarray_set(dm_args, num++, "-gfx_passthru");
+            flexarray_set(dm_args, num++, libxl__sprintf(gc, "%d", 
info->gfx_passthru));
+        }

I suppose, without it 'qemu-dm' won't  know about gfx_passthru mode and 
won't load passthru'ed vga bios.
Daniel might plan to add this code or added it already?
