On Ubuntu sudo halt doesn't poweroff the box

[marcenuc]

I've a box with default installation of Ubuntu server 11.10 configured as explained at http://vagrantup.com/docs/base_boxes.html

It works fine except for the command vagrant halt, which runs sudo halt. This command does a clean shutdown of the operating system, but does not turn off the virtual machine.

The correct command (verified from console) is:

sudo poweroff

this does a clean shutdown AND turns off the box.

Actually, I shouldn't really be using halt at all. I'm going to look into what the best suitable/portable option is for shutting down linux but I think its shutdown -h.

The following command works for me:

sudo shutdown -h now

However the man page says:

• -h Requests that the system be either halted or powered off after it has been brought down, with the choice as to which left up to the system.
• -P Requests that the system be powered off after it has been brought down.

Then it seem that the equivalent of poweroff is shutdown -P now. However -P seems to be less widely supported.
