The code in vl.c looks through the vga_interfaces[] array and warns if it cannot find the default_display there... and since there is no entry for the bochs-display in that array, you likely now always get this warning message, even if it is available? So I think you either have to drop this patch, or you've got to add an entry for the bochs-display to vga_interfaces[], too. Thomas

Mark the default graphica via the new MachineClass->default_display setting so that the machine-defaults code in vl.c can decide whether the default graphics is usable or not (for example when compiling with the "--without-default-devices" configure switch).
