How to get graphical acceleration for VNC?

[renhiyama]

I installed windows 10 VM in mvisor, in a debian sandboxed environment (I use fedora, for which dependency list were not in readme. I used distrobox, which allows gpu stuff to still run properly)

I compiled mvisor, cloned and hard reseted to mentioned commit for virglrenderer.
I installed virtio guest tools inside win10.

Then I installed mvisor-win-vgpu inside win10 via release page zip file, and it installed successfully inside powershell admin console.

I have rebooted multiple times, and yes I did enable test mode. I even added virtio-vgpu inside sample.yaml config file. and my system ram allocation is 12G.

The error/warning outputs are:

./build/mvisor -c config/sample.yaml -vnc 5900
[0.000] core/configuration.cc:275 LoadObjects() warn: object not found virtio-vgpu virtio-vgpu

I cant get this working after compiling soo much stuff 😢 can anyone help?

I am happy to share any more info if anyone needs, and I am ready to run whatever other commands I need to get this working.

Also, if I shutdown windows vm via taskbar, the vnc display says its safe to close - but then suddenly mvisor jumps cpu usage to 99%. I can ctrl+c it though to close it. Any reason for this bug?

Woops, Looks like I had to enable vgpu option in meson_options.txt and recompile the project!
I can now run gputests :)

My new question is how to get graphical acceleration for VNC, so I get to see those background blurs on app and taskbar

The driver create a new device named Mvisor-VGPU in System Devices.
This project only handle Opengl api, so it can't be seen in TaskManager.
You can use GpuTest to check if vgpu worked.

I managed to get it working @nooodles2023 , I see it in system devices list in device manager. I tried out gputest app to verify it uses my gpu. But right now I dont know of any real life app that can use this. No chrome, no minecraft java, and even counter strike 1.6 - which supposedly even has openGL option, cant play it. I am stuck with software rendering. On top of that, VNC is not native display like what spice or other VGA display couldve shown me. No 60 FPS vsync display still...
