VirtualGL with ESXi SVGA II possible?

[KAJINOFE]

Hello,

Is it possible to use VirtualGL with the following setup?

ESXi 6.5

GPU: none (no discrete GPU, no integrated GPU)

VM:  Linux (Fedora (GNOME X11) with SVGA II 3D enabled)

I'm trying to remote into the above VM with TurboVNC+VirtualGL installed on the VM and using TurboVNC on my laptop (Ubuntu) and get 3D acceleration and was wondering if this is even possible without a real GPU but with VMware's 3D offerings on ESXi.

Thank you.

I'm not 100% clear on how ESXi works, but in general, if the X server
running in the VM guest is able to render OpenGL with hardware
acceleration, then it should be possible to use VirtualGL in the VM
guest. That's the strategy for VirtualGL integration, in general. Get
3D acceleration working without VirtualGL first, then add VirtualGL.

If there is no physical GPU in the server machine, however, then there
is no point to using VirtualGL, since VirtualGL is fundamentally a
mechanism for virtualizing physical GPU resources so that those
resources can be used remotely and shared by multiple users and
applications.

Thanks for the response.  Once the VM Fedora is installed with the 3D enabled, I am able to get a proper output for glxinfo:

but after I install VirtualGL by following the doc(answered No to all 3 questions), I'm getting the following error:

*********************************************************************************************

xdpyinfo -display :0 <-- output fine

*********************************************************************************************

/opt/VirtualGL/bin/glxinfo -display :0 -c <-- I get the below error

Serial number of failed request:  25

*********************************************************************************************

My goal for all of this was to get some kind of 3D acceleration for the VM without a GPU which I think is better than nothing.  If there's an obvious error in my setup, please let me know, thank you.

That's a known bug in our distribution of glxinfo (it wasn't properly
handling indirect OpenGL environments.) Should be fixed in the latest
2.5.x pre-release build:
https://virtualgl.org/DeveloperInfo/PreReleases

One wonders why the context is indirect, however. Hmmm... When you log
into the "local" display in the VM guest and run glxinfo, is the context
still indirect? If so, then apparently it's a limitation of the ESXi
system. If not (i.e. if the context is indirect only when attempting to
access the 3D X server from the login screen), then vglserver_config
might be misconfiguring something.

Thanks I installed 2.5.3 (pre-release stable) and get glxinfo outpu.  I have absolutely no idea what I'm doing so I don't know if the below data points between the ESXi web console and the TurboVNC sessions are even meaningful at all, but here they are.
