Please download and install virtualbox *BEFORE* the tutorial. You can download it from VirtualBox downloads

Use these directions to install VirtualBox.

If your host machine is any linux system, both vritualbox and virtualbox-dkms packages must be installed.

We recommended that your computer have at least 20 to 30GB of free disk space and preferably 4GB of RAM in order to use the virtual machine.

During registration, you will receive a 16 GB USB drive with an OVA file called “CIG16_Tutorial_VM.ova.” We will use virtual box to boot up a ubuntu 14.04 linux OS.

This image contains the following packages:

• ASPECT
• ObsPy
• Rayleigh
• SPECFEM3D
• SW4
• Underworld

Download it onto the laptop you are going to use for the tutorial.

1. Run VirtualBox.
2. Select from the menu “Import appliance”:
3. Select the downloaded CIG16_tutorialvm.ova:
4. Select Next and Import:
5. Click on start (the green arrow) to launch the image:

The image contains the following users:

• aspect_user
• obspy_user
• rayleigh_user
• specfem3d_user
• sw4_user
• underworld_user

Note that all of the users listed above are password less.

The super user is cig and the password is cig.

The image does not allow any connections from the network. sudo apt-get install <package name> to install ubuntu packages.

Now simply start the CIG16 virtual machine.

If too many users are logged in at once, the next time you switch users, a password prompt is requested. However, since no users have any passwords, one would not be able to switch users at this point. Please logout after each session.
