Accesing to a VM on Fi-lab

I’m training to get familiar with the Fi-Ware Cloud service. I can create blueprints templates and instances but I cannot access in SSH or Connect to VM display. I have the server up and running, I can see the page “It works” of Apache. The problem I have are:

1. With SSH I don’t know what credential I have to use, I try with my Fi-Ware credential but the server always shows me “access denied”
2. Connect to VM display it never appears the login interface. There is some tutorial where I can see an example of how to do it or a detailed documentation how to configure and access to in a Blueprints Instance?

Usually, when you create a VM of Bluerpint, you should assign a keypair, that should be created previously. I suppose that you did it. Correct me if I am wrong. During the creation of the keypair, you could download en .pem file that it is used to access to the VM using ssh (ssh -i xxx.pem…).
