vagrant_wont_up

~/Projects/pp-development (gh:(3923957...)*) $ vagrant up
The following plugins were installed with a version of Vagrant
that had different versions of underlying components. Because
these component versions were changed (which rarely happens),
the plugins must be uninstalled and reinstalled.

To ensure that all the dependencies are properly updated as well
it is _highly recommended_ to do a `vagrant plugin uninstall`
prior to reinstalling.

This message will not go away until all the plugins below are
either uninstalled or uninstalled then reinstalled.

The plugins below will not be loaded until they're uninstalled
and reinstalled:

vagrant-aws
Bringing machine 'pp-development-1' up with 'virtualbox' provider...
[pp-development-1] Clearing any previously set forwarded ports...
[pp-development-1] Clearing any previously set network interfaces...
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"]

Stderr: 0%...

VBoxManage: error: Failed to create the host-only adapter

~/Projects/pp-development (gh:(3923957...)*) $ sudo /Library/StartupItems/VirtualBox/VirtualBox restart

Running the second line fixes it.
