tags 555296 + patch thanks Dear Maintainer,
After upgrading to Debian Squeeze, I lost my copy of "virtualbox-vm-control," so I wrote a new one. The new one is attached. This script will try very hard to stop VirtualBox VMs so the hibernation process can finish safely. Unfortunately, this script does not attempt to detect affected hardware configurations because I don't know how to do that correctly. Technical details: The script will check each user for any running VMs. For each VM it finds, it will do the following: 1. It will try to suspend the VM, as the running user. 2. If the VM failed to suspend, it will try to power off the VM, as the running user. 3. If any running VM failed to power off, it'll attempt to suspend the user's remaining VMs and then kill all the user's VirtualBox processes, as the running user. 4. If any VirtualBox process failed to die, it'll attempt to suspend every other user's VMs before killing all the VirtualBox processes. 5. By this point, no VMs should be running. If VMs failed to suspend, they were powered off. If the VMs didn't power off, that user's VirtualBox process was killed. If VirtualBox processes failed to die, all users' VirtualBox processes are killed. If even the root user couldn't guarantee all VMs were stopped, it'll quit with an error (1). 6. If no VMs appear to be running, quit normally (with 0). Please consider including this patch in future versions of Debian's VirtualBox so other users can safely combine Virtual Machines and hibernation.
