This is indeed a Ryzen CPU with Qemu/Proxmox on top of it. For GPU Passthrough to a VM the kvm.ignore_msrs=1 is often recommended. I brief test shows the VM is not working properly without this parameter, even when booting the VM with CPU:host. br, Joris -- You are receiving this mail because: You are watching the assignee of the bug.
