Troubleshoot PCIe GPU pass-through to a VM on an Ampere Altra Debian home server
I have an home lab server with an Ampere Altra Max 128-26 CPU seated in an Asrock Rack altrad8ud-1l2t. The host machine is running Debian and I can spin up virtual machines on it, however when I try to add a pci GPU, I get no display through a VNC console after the grub menu. I need help with troubleshooting this issue and help get to the end desired state of (host machine with GPU, to, virtual machine with full access to said GPU) Hardware - CPU - Ampere Altra Max 128-26 - Motherboard - Asrock Rack altrad8ud-1l2t - GPU - Nvidia RTX A6000 Software (somewhat open to changes) - Host OS - Debian with an arm port of Proxmox VE GitHub - jiangcuo/pxvirt: A fork of Proxmox VE for ARM and LoongArch architectures. - Guest VM - QEMU Ubuntu server - Guest VM target use - Nvidia container runtime
What I’ve done/ noticed so far: - Bios enabled SR-IOV Support - Host Kernel, blacklisted modules to try to prevent the host from using the GPU - Guest kernel, blacklisted modules to try to prevent the guest from using the GPU - The Ubuntu Installer works which makes me think that this is a driver issue"
Please share any insights / solution if any
Thanks
Andre
