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.
