The physical memory address bits that are reported to the guest OS. Should be smaller or equal to the host's. Set to 'host' to use value from host CPU, but note that doing so will break live migration to CPUs with other values.

+`vga`: `[[type=]<enum>] [,clipboard=<vnc>] [,memory=<integer>]` ::
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 them self.
You can also run without any graphic card, using a serial device as terminal.
+`clipboard`=`<vnc>` ;;
+
+Enable a specific clipboard. If not set, depending on the display type the SPICE one will be added. Migration with VNC clipboard is not yet supported!
+
`memory`=`<integer> (4 - 512)` ;;
Sets the VGA memory (in MiB). Has no effect with serial display.
The VM generation ID (vmgenid) device exposes a 128-bit integer value identifier to the guest OS. This allows to notify the guest operating system when the virtual machine is executed with a different configuration (e.g. snapshot execution or creation from a template). The guest operating system notices the change, and is then able to react as appropriate by marking its copies of distributed databases as dirty, re-initializing its random number generator, etc.
Note that auto-creation only works when done through API/CLI create or update methods, but not when manually editing the config file.
