I deleted the directory that contained the .vagrant file. When I up a new VM it's complaining about ports being in use. So how do I destroy a VM without having it's .vagrant file?
The following VirtualBox commands might help. If poweroff doesn't work, try unregistervm.
$ VBoxManage list runningvms
$ VBoxManage controlvm <uuid> poweroff
$ VBoxManage unregistervm <uuid>
Shell script to stop all running vms:
VBoxManage list runningvms | awk '{print $2;}' | xargs -I vmid VBoxManage controlvm vmid poweroff
