Vagrant is a tool for building and distributing development environments.

Vagrant::MachineIndex#set

Creates/updates an entry object and returns the resulting entry.

If the entry was new (no UUID), then the UUID will be set on the
resulting entry and can be used. Additionally, the a lock will
be created for the resulting entry, so you must {#release} it
if you want others to be able to access it.

If the entry isn't new (has a UUID). then this process must hold
that entry's lock or else this set will fail.
