Headless Proxmox. Does VNC require a GPU.

[Dawdie]

My current plan for proxmox is to have a windows server with a dedicated graphics card and some smaller VM's with no dedicated card. Am I right in assuming Proxmox would require its own graphics card to support VNC via the web GUI for any machine that doesn't have its own dedicated card?

I currently have it configured with Proxmox having an AMD card and my windows host with a Nvidia card, I would like to remove the AMD card if possible.

Thanks

no the vnc functionality has nothing to do with physical graphics cards...
(you can still access the vms with novnc even on a headless pve)

I would like to remove the AMD card if possible.

that may be tricky since the kernel tries to use the first gpu it finds for printing and so on, but this can be configured
search the forum for headless gpu passthrough or passthrough efifb and you should find some threads about it

Great to hear.

Wondering if you have any recommended guides. I tried a fair few of them and the VM always boots up with a black screen in headless mode (GPU never gets to the login page so I assume the GPU isn't loaded on the host and it purges / goes black when I start the attached VM up. VM boots up fine with the AMD card also connected.



After fumbling for hours I finally found the problem. Disabling CSM gets the VM to take the card properly
