Hi Team!

I installed Proxmox on debian 11 on server with 2 * Intel Xeon CPU E5-2680 v4 @ 2.50GHz.

Proxmox is starting well.

I have software that installed as VM and used nested virtualization. It is software work well on esxi 6.7 on same HW (but have limitation as you know 8 vcpu on esxi free).

In this software I creating different topologies using LXC and VM.

The problem is that LXC starting / working well, but VM not started

Support from this software tell me that may be is problem "either a compatibility problem between your Proxmox and hardware or how Proxmox expose the CPU to our software".

How to check that Proxmox does support HW with Intell CPU E5-2680 v4 ?

Thanks!

Did you set the CPU type to host for the VM? (YourNode -> YourVM -> Hardware -> Processors -> Edit -> Type: host)

Also check that KVM is enabled (should be by default) for the VM. (YourNode -> YourVM -> Options -> KVM hardware virtualization -> Yes)

Both of these settings were as you indicated, but did not work. Installed qemu-kvm on same HW - everything works fine.
 
Have you read this? Can you please post your VM-configuration (/etc/pve/qemu-server/<vmid>.conf)?

By selecting different CPU types it works with cpu: Broadwell (code name) -- not cpu: host

args: -cpu Broadwell,+vmx,kvm=on,+pdpe1gb,+vme
cores: 28
cpu: Broadwell
