Krisztian, thanks for your reply!
It might be a dumb question, but how to access the virtual machine's file system?
I'm trying to use documentation provided with VM in the cloud and it says to use WinSCP. So, I've entered my IP, and user 'root'. The password is a problem... again. Then, from the documentation I've read "Use the private key (downloaded during the activation of the instance in SAP Cloud Appliance Library) for login with the root user.". Ok, I have it, but WinSCP doesn't accept it (it says it can use only compatible with Putty keys). I'm stuck...
