[Resolved] Ubuntu 19.10 guest, Win10 host: 3D accel. enabled, not working

[Underground78]

Hello,

I am trying to get 3D graphic acceleration to work with a Ubuntu 19.04 guest OS (on a Windows 10 host). Edit: The same issue happens with Ubuntu 19.10.

I have been reading this blog post : https://blogs.oracle.com/scoter/oracle- ... 1804-guest. It seems pretty straightforward but I cannot seem to make it work...

I have selected "VMSVGA" graphic controller and ticked "Enable 3D acceleration" in the VM configuration. I have installed the guest additions in the guest OS.

If I check with "glxinfo", it is still using the software renderer:

Code: Select all

$ glxinfo | grep OpenGL
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: llvmpipe (LLVM 8.0, 256 bits)

I have attached the VM log (zipped because it was bigger than 128 KB).

I hope someone will see what I am missing here...

I'm seeing "VMWare" mentioned, which tells me that you are indeed using the VMSVGA graphics controller (VMSVGA == VMware compatible SVGA).

Beyond that, someone more experienced with Linux guests will have to comment.

However, does OpenGL work correctly on your host? AFAIK, 3D acceleration in a guest still requires working OpenGL on the host.


Incidentally, you need to reduce the number of cores allocated to the guest. Your host has 4 cores, so giving 4 cores to the guest leaves the host with 0 cores. That means that guest and host can interfere with each other. Yes, your CPU has 8 threads, except we don't care about threads. I also think you've allocated too much RAM: out of 11GB available, you've allocated 8GB. Not such good news for the host. The idea is to strike a balance of resources so both guest and host can run smoothly. Consider how much RAM (and CPU) the guest actually needs.

Not sure why you think it's not working, this is exactly what's supposed to happen. Can you tell me why you think that this is software rendering?


BACKGROUND CHECKS
You need to take a look at several places to verify things are alright:

00:00:02.491746 [/Devices/vga/0/Config/] (level 4)
...
00:00:02.491752   VMSVGA3dEnabled    <integer> = 0x0000000000000001 (1)  <-- 3D acceleration is enabled
00:00:02.491753   VMSVGAEnabled      <integer> = 0x0000000000000001 (1)  <-- The new vGPUs are in use, VMSVGA or VBoxSVGA
00:00:02.491754   VMSVGAPciBarLayout <integer> = 0x0000000000000001 (1)  <-- VMSVGA is used
00:00:02.491754   VMSVGAPciId        <integer> = 0x0000000000000001 (1)  <-- VMSVGA is used
00:00:02.491755   VRamSize           <integer> = 0x0000000008000000 (134 217 728, 128 MB)[/color]

The second part, is looking for clues for the Guest Addition (GAs) installation:

00:00:21.567580 VMMDev: Guest Additions information report: Version 6.0.12 r133076 '6.0.12'
...
00:00:45.001460 VMMDev: Guest Log: 08:57:58.333395 main     VBoxService 6.0.12 r133076 (verbosity: 0) linux.amd64 (Sep  3 2019 11:48:42) release log

And finally from within the guest, you look for evidence that the GAs are indeed loaded:

$ VBoxControl -version
6.0.12r133076

$ lsmod | grep vbox
vboxsf                 77824  0
vboxvideo              36864  0  <-- Video kernel module is enabled
vboxguest             344064  6 vboxsf
ttm                   106496  2 vmwgfx,vboxvideo
drm_kms_helper        172032  2 vmwgfx,vboxvideo
drm                   401408  8 vmwgfx,drm_kms_helper,vboxvideo,ttm

Sorry I forgot to subscribe to this thread so I thought it didn't get any answer.

I'm pretty sure it's using software rendering because of the "glxinfo" ouput. The Oracle blog post says "[if the] OpenGL Renderer is NOT "SVGA3D", then you are NOT using the correct OpenGL drivers" and in my case it says "llvmpipe (LLVM 8.0, 256 bits)" (which is similar to what they show for the "not working" example).

Also the glmark2 figures I get are lower than what I would expect with hardware rendering (e.g. "FPS: 1493" in the blog post, more like "FPS: 200" in my case).

However, does OpenGL work correctly on your host? AFAIK, 3D acceleration in a guest still requires working OpenGL on the host.

Not sure how I can check that?

I seem to remember that there's a portable test app called glxgears that people sometimes use for that. It's a bit dated, and it is not a benchmark, all it establishes is whether you have a working OpenGL framework on your host.

[Underground78]

Thanks, it seems to work fine.

[towo2099]

It should look like:

Code: Select all

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: SVGA3D; build: RELEASE;  LLVM;
OpenGL version string: 2.1 Mesa 19.1.6
OpenGL shading language version string: 1.20
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 19.1.6
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16
OpenGL ES profile extensions:

Then 3D is working in guest. And for VMSVGA it needs xserver-xorg-video-vmware installed in the guest.

Code: Select all

Graphics:  Device-1: VMware SVGA II Adapter driver: vmwgfx v: 2.15.0.0 
           Display: x11 server: X.Org 1.20.4 driver: vmware unloaded: fbdev,modesetting,vesa 
           resolution: 1440x900~60Hz 
           OpenGL: renderer: SVGA3D; build v: 2.1 Mesa 19.1.6

[Underground78]

It should look like

Thanks for the confirmation.

And for VMSVGA it needs xserver-xorg-video-vmware installed in the guest.

I was already installed so I tried removing it and reinstalling it but no change.

[towo2099]

It could be something is wrong in your graphics configuration of your host.

[Underground78]

Possibly but I have no idea how to make sure of that...

[towo2099]

Possibly but I have no idea how to make sure of that...

Since no one knows your host hardware, ....

[Underground78]

Nobody asked so not sure what you need exactly.

Code: Select all

Processor: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz (8 CPUs), ~3.4GHz
   Memory: 16384MB RAM
Card name: NVIDIA GeForce GTX 650 Ti

[towo2099]

Hm, host OpenGL should available with that card. Can you paste teh Xorg.0.log from Ubuntu?

[Underground78]

Hmm, as far as I can tell the log does say that the driver failed to enable 3D acceleration but it doesn't say much about why.

[towo2099]

hm,

Code: Select all

dpkg -l | grep -i mesa

is showing what?
