Is there a host-passthrough vs host-model distinction in Proxmox? Can only see 'host'

[marcosscriven]

Generally with my Ryzen 3900x I'd use 'host-passthrough', but in Proxmox I only see 'host'. When I used 'host' in Proxmox, my Windows 10 VM crashed.

It works with EPYC IBPB however.

Which should I use?

Do you mean for the CPU type?

When I used 'host' in Proxmox, my Windows 10 VM crashed.

It works with EPYC IBPB however.

Is Hyper-V installed on the Windows VM by any chance? WSL 2 would also cause Hyper-V to be installed.

Or does the VM give you more information when it crashes?
