how to enable vgpu?

how to enable vgpu? when i enable the "vgpu" option in meson_options.txt,compiler report an error like below：

My host is Deepin V23 .

Build virglrenderer from Mesa on host, these virgl_xxx functions was implemented in official libvirglrenderer.so

什么意思？是可以不打开vgpu选项就可以直接使用？因为我目前的状态是meson_options.txt中不开vgpu选项就可以正常编译安装并创建虚拟机安装系统。

Yes. You don't need to enable the vgpu option unless virgl is what you want.

目前是我在不打开vgpu选项情况下，我可以正常编译通过并运行成功，也能正常安装win11系统，但在win11的设备管理中看不到“Mvisor VGPU“设备，同时启动时终端会报一个错：
[0.000] core/configuration.cc:275 LoadObjects() warn: object not found virtio-vgpu virtio-vgpu
我的vm yaml配置文件中打开了关于vgpu的配置：

• class: virtio-vgpu
  memory: 2G
  staging: Yes
  blob: No
  node: /dev/dri/renderD128 #这是我主机中查到的渲染设备编号
  请问要如何处理？

[nooodles2023]

如果你不需要vgpu可以把virtio-vgpu从配置文件里面删掉，这样就不会有警告并且设备管理器也不会有未知设备了

[nooodles2023]

virtio-vgpu是为了给windows的客户端程序提供opengl4的支持

我就是向着vgpu来的，平时主要使用qemu，但是困扰于它没有3d加速好多年啊，最近才看到你们的项目解决了这个问题，准备研究研究，成功了就在深度论坛里发个帖子。

https://gitlab.freedesktop.org/virgl/virglrenderer 在host上编译这个项目就可以开启vgpu编译mvisor
https://github.com/tenclass/mvisor-win-vgpu-driver 这里是guest驱动，项目是参考了virgl和qemu在linux下的工作方式，迁移到了windows和mvisor上

两个项目都编译安装成功了，但是在启动windows11的时候会蓝屏，且主机喇叭异响。附件是打开了debug参数后启动win11的日志以及蓝屏截图，有几次蓝屏上还提示 what failed：vgpu.sys.
vgpu-debug.txt

[nooodles2023]

vgpu的guest驱动编译的是win10的版本，没有在win11上测试过，你可以在win10上测试一下。
后续可以在tenclass/mvisor-win-vgpu-driver#13 这个问题上讨论

另外发现一个bug，安装了guest-tools后（版本229），guest系统关机会卡在关机界面。

直接关闭窗口后，终端有个error,不知道是不是有关系。
