    5700G passthrough?

    Has anyone done passthrough an AMD 5700G iGPU to any VM? Good igpu, it is a pity that it would be wasted if you could, for example, transcode.

    [SOLVED] True Headless PVE with single GPU passthrough

    I have a home lab setup using a relatively low specced Ryzen5 2600x (no integrated graphics). My Mobo has VGA and DV ports, but presumably these will only work if the CPU has a built-in GPU. I also have a nvidia 1080ti mounted in a PCI-e slot which I'd like to use with PCI Passthrough, however...

    Upgrading Proxmox from 6.2 to 6.4 broke GPU Passthrough

    Hello guys. I had a Proxmox server running fine for about a year with two VMs, one Windows and one MacOS, each with their own GPU (RTX 2080 Super and Vega 64 respectively). For some dumb reason I decided to upgrade my server, and already in the process (after upgrading to 6.4) I started to have...

    NVidia allows PCIE Passthrough in latest drivers.

    Apparently in the latest Nvidia drivers they have added "Beta" support of pci passthrough of graphics cards. So no more masking the VM, just directly passthrough the GPU. Of course you still have to make sure the host system is not using the card. Take a look at GeForce PCIe Passthrough...

    No video from VM if iGPU not connected to monitor. Must BOTH Intel iGPU and discrete GPU be connected?

    I have a monitor connected to the Nvidia card in my Proxmox box and have successfully passed it through to a Linux VM. However I find that I must also have the onboard Intel iGPU connected to the monitor for it to work (even if not switched to that input on the monitor), otherwise I just get a...
