How can I capture current configured ssh guest port?

[Joaquin Menchaca]

How can I capture the current SSH guest port and private key location from Vagrant file?

I tried using this in my Vagrant file:

 puts "config.ssh.private_key_path=#{config.ssh.private_key_path}"
 puts "config.ssh.guest_port=#{config.ssh.guest_port}"

But I get object ids.  I then tried to inspect the objects, but all I get is an object id... :'(
