Following this Opennebula quickstart guide on Ubuntu 12.04, I was able to create and instantiate a CentOS 6.4 virtual machine. However, I don't know what login credentials to use (i.e. username and password) to remotely access the vm. I can ping the vm and onevm list command is saying it's running. I've already tried oneadmin and the password inside ~/.one/one_auth file but it's not working. I also tried root with no password, and oneadmin with opennebula as password. But still, it's not working. Here's a snapshot of the VM created: 
Apologies if the question is too simple. It's just that I don't see any username/password to be used or to be set on the guide, for the virtual machine created. Thanks in advance!
