[SOLVED] Can't get mixed mode vGPU to work on NVIDIA A40

[espenu]

I have an NVIDIA A40 card (570 driver) with vGPU working with a couple of VMs. But I can't get mixed mode vGPU to work.
If I select for example a 4Q profile on one VM and start it, the only options for other VMs are 4Q and 4A.
What do I need to do to enable mixed mode on this card?

nvidia-smi shows vGPU Heterogeneous Mode = Disabled.

You can follow the guide [0] to enable vGPU Heterogeneous Mode

Thank you so much! I was looking at this from a completely wrong angle.
"nvidia-smi vgpu -i 0 -shm 1" is the answer.

Does anyone know how to correctly make this apply across reboots? This is lost on reboot and VMs fail to start

I've ended up giving one large profile to a VM instead of splitting it, so I'm not actually using heterogeneous mode any more.
But, it should be possible to run the command at linux startup using systemd. Just make sure that it runs after the nvidia vgpu service has started.
