I'm trying to get 3D acceleration to work in virt-manager, but no matter what guest I use in virt-manager, if I enable 3D acceleration, I get this error.

In the details of the error, it has this:

Error starting domain: internal error: process exited while connecting to monitor: 2023-04-14T06:53:32.967256Z qemu-system-x86_64: egl: eglInitialize failed
2023-04-14T06:53:32.967390Z qemu-system-x86_64: Failed to initialize EGL render node for SPICE GL

Traceback (most recent call last):

2023-04-14T06:53:32.967390Z qemu-system-x86_64: Failed to initialize EGL render node for SPICE GL

Here are the settings I have configured for my virt-manager instance:

Video:

<video>
  <model type="virtio" heads="1" primary="yes">
    <acceleration accel3d="yes"/>
  </model>
  <address type="pci" domain="0x0000" bus="0x00" slot="0x01" function="0x0"/>
</video>

Graphics Type:

<graphics type="spice">
  <listen type="none"/>
  <image compression="off"/>
  <gl enable="yes" rendernode="/dev/dri/by-path/pci-0000:05:00.0-render"/>
</graphics>

What does egl: eglInitialize failed and Failed to initialize EGL render node for SPICE GL mean? How do I fix this error? And why does this occur? Am I missing something important?

And just to confirm, I have checked to see if I've got virtualisation enabled in GRUB with the grep CMDLINE_LINUX_DEFAULT /etc/default/grub command, and yes I do:

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt splash"

The GPU I'm using for the host machine is NVIDIA GeForce GTX 950, with the latest proprietary nvidia driver installed. And it is the only GPU I have.

I've even tried running DRI_PRIME=1 virt-manager, but it doesn't work.

I've even looked everywhere for this error, and even looked here and here.

I've even looked here, but that solution didn't work.

How do I get 3D acceleration to work in virt-manager?

  • What is the version of Ubuntu you are using? – David Apr 14 '23 at 09:45
  • 22.04.2 LTS is the version I'm using, latest LTS release. Memory is 16.0 GiB, processor is Intel® Core™ i3-6100 CPU @ 3.70GHz × 4. – Platinum Lucario Apr 14 '23 at 12:47
  • Hi, been trying to fix this for a while, but always came to the conclusion that it's not supported by Nvidia. You could theoretically try it with mesa drivers, but I haven't tried that since I'm using software which requires close sourced drivers. Anyways, if you find a solution, please let me know! – TDiblik Apr 14 '23 at 22:43
