Proxmox reboots itself when doing a shutdown

[dragonauta]

Hi, I have a single proxmox node.
When I try to shutdown, it stops all CT & VM and then reboots again.
I can't find how to effectively poweroff the server.
I stopped all CT & VMs manually and then tried from web interface and from command line: poweroff, shutdown now, runlevel 0
Reboots every time.
I've checked on BIOS and options for restoring power are disabled.

Its 'shutdown -h now'

Thanks mir, it worked.
But why doesn't work if I use web interface?

My guess is that you have a buggy BIOS or the ACPI implementation in your BIOS is buggy.
