+- `vga` (Attributes) Configure the VGA Hardware. If you want to use high resolution modes (>= 1280x1024x16) you may need to increase the vga memory option. Since QEMU 2.9 the default VGA display type is `std` for all OS types besides some Windows versions (XP and older) which use `cirrus`. The `qxl` option enables the SPICE display server. For win* OS you can select how many independent displays you want, Linux guests can add displays themself. You can also run without any graphic card, using a serial device as terminal.
