+See <http://blog.codeboutique.com/post/creating-debian-squeeze-box-for-vagrant>
+
+    vagrant ssh-config vmname | ssh -t -t -F/dev/stdin vmname
+
+Use the -t -t to overcome the pseudoterminal warning
+
+- Now use a control connnection for ssh
+(as it seems that the cli invocation of vagrant takes a couple of seconds ....)
+
+Setup the control session:
+
+    vagrant ssh-config vmname | ssh -t -t -F/dev/stdin -o 'ControlMaster auto' -o 'ControlPath ~/.ssh/vagrant' vmname
+
+
+Use it for fast login
+    ssh -o 'ControlMaster auto' -o 'ControlPath ~/.ssh/vagrant' vmname 
+
+Now it logins in a matter of milliseconds!
