VBoxManage: error: Failed to create the host-only adapter (II)

The solution to this problem appears to be the same as reported in the related post:

Although the VM in the Oracle VB GUI appears as not running, you must manually start it through Oracle VB GUI (this should work and allow you to login to the box) and then manually power it off again (also through Oracle VB GUI). Then, run vagrant up again and it should work.

If you’re having issues with this setup then please add comments to this post.
