KVM 3d Acceleration

[Gund4m]

Hi all, is there a way to get graphics 3d acceleration on Windows 7 Guest machine?

i followed this tutorial for install the guest vm.

Thanks in advance for the response

you can pass your GPU through to the windows machine:

do you want 3D acceleration in spice (for remote), or do you want pci passthrough your vga card (for local) ?

for spice, it's not yet available in proxmox. we need to add support for virtio-gpu and other 3d stuff. (and I think that only recent linux guest support it, not yet windows guests)

Are there any updates when virtio-gpu Support will be available?
My last info was that is already available:

We want to see 3D in SPICE (not local), we can use pci passthrough. Is it possbile in PVE 5.1?

Thanks.

Hi,

Only pcie passthrough is possible.

Hi,

Dear wolfgang, what are you mean? Do you mean that I can't use 3D with SPICE? Only for local?

Best regards,
Viktor.

 

[wolfgang]

Correct, only local.

 

[VGusev2007]

Correct, only local.

Ok. I think it will be good if proxmox will implement this. Thank a lot for you answer!

May I ask what's the status of this?

In particular, is it possible now (June 2021) to use 3D acceleration in a Linux guest using Spice connecting from a remote computer (on LAN)? If so, can you please point me to the right doc/resource?

I try to use a Linux VM, connect remotely and even Chrome is sluggish due to the eyecandy it is doing.

I'm also curious. It would solve the problem running virtual Linux Mint with Cinnamon, which complains that "your system is currently running without video hardware acceleration". Searching the web explained this means there is no 3D acceleration, which apparently is possible to enable in VirtualBox through "Guest Additions" (the article is from 2013), but not yet in Proxmox?

Ha! After over 20 hours playing with virtually all settings in Proxmox including PCI passthrough I found why my guests where laggy!!!

3D acceleration disabled in Proxmox.

To test this I simply unchecked 3D accel setting in VirtualBox when installed in Linux host on that same physical machine I use Proxmox (Proxmox is on another HD) and I have very very similar laggy performances than when I run my guests in Proxmox!

I need 3D accel in SPICE, what can we do?
I'll continue googling, cuz without this I cannot use Proxmox.

Is there any possibility to do 3d acceleration in proxmox, in the latest version 8.2? I haven't found any information

It is possible but limit. I use PCI passthrough + rdp for that. OS guest is Windows.

Maybe you give the VM too many of the host resources? If you want low-latency then make sure not to stress the host.

Yes, Proxmox is designed for enterprises not 3D.
