			This implements the VM Generation ID feature by passing a 128-bit GUID to the guest via a fw_cfg blob. Any time the GUID changes, an ACPI notify event is sent to the guest The user interface is a simple device with one parameter: - guid (string, must be "auto" or in UUID format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) Signed-off-by: Ben Warren <ben@skyportsystems.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> Tested-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Michael S.
