From c2b3b41a0ba22b22e199f0a53830f337989db9fd Mon Sep 17 00:00:00 2001 From: aliguori Date: Thu, 15 Jan 2009 20:37:28 +0000 Subject: add a -vga none cli option (Stefano Stabellini) currently there is no way to fully disable any graphic card device for the PC architecture. You can have no graphical output, thanks to -nographic, but you would have the VGA device connected to your PCI bus anyway. There is already a convenient -vga option to choose between std, cirrus and vmware; this patch add the new option "none" to select no graphic card at all.
