[Fiware-lab-help] Keypair issue

[José Ignacio Carretero]

Hi,

You need a private key in order to connect to your VMs. You have 2 options:

1. Create the Keypair (private + public key) in your own host and UPLOAD 
the public key to fiware Cloud Portal.

2. Create a Keypair in FIWare Cloud Portal, and DOWNLOAD the private key

--- We NEVER EVER keep your Private Key. If you loose it, then nothing 
can be done in order to get it back again. It is your responsibility to 
keep that file safe. Thus, we can't provide you any link to your Private 
Key.

However, if you choose Option 2 In cloud Portal (Security --> Keypairs  
--> Create Keypair), After creating a new keypair, you can see a 
"Download Keypair" link where you can click in order to download the 
Private Key. That is the file you should have had downloaded and which 
must have a name "KeyNolb.pem" in your case. But It seems you are trying 
to use a file you don't have, so It can't be found.

Please, create a new Keypair, download the Private Key and do as you are 
doing with "KeyNolb.pem".

Best regards,
José Ignacio
