    • Name: build, type: Linux:
      • Select 2GB of RAM
      • Hard disk: take the defaults: 8 GB and Create a virtual hard disk now
      • Hard disk file type: VDI
      • Storage on physical hard disk: Dynamically allocated
      • File location and size: type "build" for the name
    • Click on settings for the build VM:
      • Storage: Controller IDE – click on the disk with a + sign symbol to add an optical drive. Choose disk: browse to the location of the downloaded iso file.
      • Add a 2nd network adapter for host-only network (see the screenshot in the section for Creating onos-scratch VM.)
      • System: Motherboard tab – uncheck floppy, move optical to the top in the Boot Order box.
    • Install Ubuntu (use the same credentials as for the first Ubuntu VM). When the installation completes, power the VM on and login.

  • Generate a SSH public key on your build machine if you hadn't done so in the past.
    Login to the build machine and run the following command:

    Code Block
    languagetext
    build:~$ ssh-keygen -t rsa

    The default options and no password are fine for this tutorial.

  • Verify connectivity. From the build machine you should be able to SSH to the VM using the IP address assigned to eth1:

    Code Block
    languagetext
    build:~$ ssh -l sdn 192.168.56.101

    If the ssh connection failed make sure that the openssh-server is installed by running:

    Code Block
    languagetext
    $ sudo apt-get install openssh-server

    Check that you can ping the onos-scratch VM by IP from the build machine and reverse, for example:

    Code Block
    languagetext
    sdn@build:~$ ping 192.168.56.101

    Close the ssh connection to the onos-scratch VM.
