Need help: "sorry, this application cannot run under virtual machine"

[cjgawatama]

Hello everyone,
I am trying to use Proxmox 8.2.4 to run a game server on CentOS 7, and I am encountering the following error: "sorry, this application cannot run under virtual machine"


this is my config file:

args: -cpu host,-hypervisor,kvm=off
boot: order=scsi0;net0
cores: 4
cpu: host,hidden=1,flags=+pcid
memory: 8192
meta: creation-qemu=9.0.2,ctime=1725881141
name: Jx-Server-Centos-7
net0: virtio=BC:24:11:31:C1:50,bridge=vmbr0,firewall=1
numa: 0
ostype: l26
scsi0: HDD:505/vm-505-disk-0.qcow2,iothread=1,size=100G
scsihw: virtio-scsi-single
smbios1: uuid=b01da070-1bbc-41f3-a455-e8720aaaa1a2
sockets: 1
vmgenid: 6e72b5ef-68cd-4133-b357-eff361d30694

I hope someone can help me fix this issue. Thank you

This doesn't seem to be a PVE-related problem, but with the VM detection algorithm used by the game server you want to start. You could try read the source code if "server_start" is a simple shell script and if there are some VM checks you could comment them out, but it would be harder if its a binary.

Anyway, personally, I wouldn't trust an application that doesn't allow me to run it inside a VM (as that would indicate to me that it wants access to a real physical machine), but usually they will check for hardware information and check the processor name and so on for some common virtualized device names, e.g. "QEMU PCI-PCI bridge", "Red Hat, Inc. Virtio SCSI", etc.

My bad, I just noticed that you're already passing args: -cpu host,-hypervisor,kvm=off and cpu: host,hidden=1,flags=+pcid to the VM already. It would be helpful to have more information on the game server you're trying to run, but in general it's quite easy for an application check if it's running in a virtual machine.
