I built a proxmox cluster with 7950x. Every no= de that I tested on would hard reset with no logs when a VM was doing nested virtualization. Our CI testing uses VMs, and putting the CI in a VM itself makes it pretty = easy to reproduce, just takes some time. Setting kvm_amd.vls=3D0 seems to have resolved the issue, we had zero node = resets today and I was trying to force them. Kernel is Proxmox's 6.8.12-1-pve.
