I deleted a folder containing a running Vagrant box before realising it was still running.
How can I delete it from Vagrant (global-status) now?
I already removed the Virtualbox VM.
To discard old boxes listed in vagrant global-status
(eg. you deleted the folder containing the .vagrant
dir from the filesystem) you just need to run:
vagrant global-status --prune
You might need to remove the Virtual Machine directly from your provider (VMWare, Virtualbox, ..) control interface.
