I’ve found I occasionally run into an odd Vagrant error every now and then:

There was an error while executing
`VBoxManage`, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below.
Command: [“hostonlyif”, “create”]

For me, this sometimes happens when I try to re-instantiate a virtual
machine after my laptop’s battery has died and OSX has attempted to
restore state. Other people seem to encounter this error under different
conditions; even immediately after installing Vagrant and attempting to
spin up a virtual machine for the first time.

Run the following command to bounce VirtualBox:

sudo /Library/StartupItems/VirtualBox/VirtualBox restart

and now running:

vagrant up

should go off without a hitch.
