Auto close Guest OS before ubuntu shutdown?

[grassvalley]

I want auto close guest os before ubuntu shutdown, How can I do?

Sorry ?my English is so bad.

In your shutdown script you should call

VBoxManage list vms

and search within that list for VMs with a running state. Then enumerate over these VMs and do

VBoxManage controlvm poweroff

or

VBoxManage controlvm acpipowerbutton

I can't write script, can you give me a script for this ?
I host OS is ubuntu 7.10.
Thanks.

"VBoxManage controlvm poweroff vm_name" would shutdown the host computer. However this is like pushing the power button of a computer, that is to say, the state of the guest os will not be saved and it could even lead to data corruption on the guest computer. A better way to do is to ssh to the guest computer and issue a "shutdown -h now" command if the guest is a Linux os. You can make it even better by implementing password-less ssh access to the guess os so the command can be issued from the host computer.

Then use the second method (acpipowerbutton).
