How do I associate a Vagrant project directory with an existing VirtualBox VM?

Question

Somehow my Vagrant project has disassociated itself from its VirtualBox VM, so that when I vagrant up Vagrant will import the base-box and create a new virtual

This is modified from @Petecoop's answer.

Run vagrant halt if you haven't shut down the box yet.

Then list your virtualboxes: VBoxManage list vms

It'll list all of your virtualboxes. Identify the box you want to revert to and grab the id between the curly brackets: {}.

Then edit the project id file: sudo nano .vagrant/machines/default/virtualbox/id (from the project directory)

Replace it with the id you copied from the list of VBs.

Try vagrant reload.

If that doesn't work and gets hung on SSH authorization (where I stumbled), copy the insecure public key from the vagrant git. Replace the content of /.vagrant/machines/default/virtualbox/private_key. Backup the original of course: cp private_key private_key-bak.

Then run vagrant reload. It'll say it's identified the insecure key and create a new one.

default: Vagrant insecure key detected. Vagrant will automatically replace
default: this with a newly generated keypair for better security.
default: Inserting generated public key within guest...
default: Removing insecure key from the guest if it's present...
default: Key inserted! Disconnecting and reconnecting using new SSH key...
==> default: Machine booted and ready!

You should be all set.
