X-forwarding in Vagrant

I was trying to get x-forwarding work on vagrant for using mysql workbench on my dev vagrant box and was able to do that by adding following to my vagrant file

Vagrant.configure(2) do |config|
...
config.ssh.forward_x11 = true
end

And after VM is up
vagrant ssh -- -X
was all I had to do to get it working. I started liking vagrant more and more everyday.
