[SOLVED] Single GPU passthrough + NoVNC/Spice/SSH access?

[p3ter_b]

I have an AMD CPU with an nvidia GeForce RTX 3060 - as *only* GPU.
The CPU doesn't have on-chip-graphics, so I have no onboard monitor output option.

Is it still possible to passthrough my nvidia without breaking my setup?
So that my bare-metal host becomes literally "headless" - and I access it (as usual) only per remote console (NoVNC, SPICE or SSH)?

`lspci` in my VM already shows the nvidia card (+audio).
But I don't know how to test/benchmark it yet.

Grateful for any experiences.

It works.
As expected, I don't get any image from the host-system on the physically connected screen anymore, but all the virtual machines and containers are seamlessly accessible just like before.

Remotely with NoVNC, Spice and SSH.
All good!
