Nested Virtualization | Facter Shows KVM not Physical on VMs

[nhlax2_maduna]

Hi All,

I have an issue where a VM running under proxmox 8.2 shows as a kvm (even with CPU:host ) when using facter command.
I was expecting it to show as physical, so puppet can successfully deploy and run its nested VMs.

Below are tests from a Staging Server running under Proxmox and a DR Physical Server.
I hope to get a solution that can ensure the VM appears as a physical machine aslo, when using facter, once I select CPU: host on proxmox.

Thanks for all prompt responses.

Proxmox does not hide that it's a VM. See this recent thread for some examples of hiding it (there are other threads about hiding for games as well): https://forum.proxmox.com/threads/n...-run-under-virtual-machine.155015/post-706254

Thanks for the response, I am changing the CPU flags and will share the outcome.

Update:
No luck, same issue - VM is running an appears and kvm

Current CPU flags:

24091217.conf: cpu: host,hidden=1,flags=+pcid
24091217.conf: args: -cpu 'host,+kvm_pv_unhalt,+kvm_pv_eoi,kvm=off'
