I have several Ubuntu 10.10 (Maverick Meerkat) servers running in VirtualBox 4.0.4 (however this issue was also present in VirtualBox 3.2.8). When I issue an ACPI shutdown to the VMs, nothing happens.

I have added acpi=force to the top of /etc/default/grup (and ran sudo update-grub), and I have added agm_power_off=1 to /etc/modules.

I am at a lost for what to try next.

  • Can you show us the log? did you try in your terminal as root VBoxManage controlvm 'virtualmachine' poweroff

Ubuntu Server doesn't ship with ACPI support installed. See this thread for the original answer: link

To install ACPI support in Ubuntu, type this into a shell:

sudo apt-get install acpid
