  1. To develop with a Virtual Machine (VM), your computer should have at least 8GB of RAM and a 64-bit host OS. AMD-V or Intel VT-x are also required (most computers have these). Submitty is RAM and I/O intensive, so more RAM and a fast disk are better.

  2. Enable Virtualization

  3. Download and install VirtualBox, Vagrant, and vagrant-vbguest.

    These versions and “host” operating system combinations have been tested and known to work for the project:

    OS VirtualBox Version Vagrant Version Notes
    Windows 7 SP1 4.3.36 1.8.1  
    Windows 10 Education 5.0.20 1.8.1  
    Mac 10.9.5 4.3.36 1.8.1  
    Mac 10.11.6 5.0.26 1.8.4  
    Mac 10.11.6 5.1.2 1.8.5 Could not establish link to VM on vagrant (broken shared folder)
    Fedora 22 4.3 1.7.2 Didn’t work, conflict with installed vmware?

    Below are quick steps to get everything installed and running. You can just go to the respective sites and downloaded the necessary binary (which you must do for Windows).

    Mac Installation
    Install homebrew if you don’t have it and then run:

     brew cask install virtualbox
     brew cask install vagrant
     sudo vagrant plugin install vagrant-vbguest

    Ubuntu Installation

     sudo apt-get install virtualbox
     sudo apt-get install vagrant
     sudo vagrant plugin install vagrant-vbguest
  4. Clone the Submitty repository to a location on your computer (the “host”).

    git clone
  5. Navigate to that directory on your computer in a shell/terminal and type:

    vagrant up

    Vagrant will build your VM. This will take maybe 30 minutes to a few hours depending on your Internet connection speed. When this command finishes, your VM is ready to use.

  6. To stop and restart the VM:

    • When you are finished working, you can suspend the virtual machine (save state, a little faster to restart):

      vagrant suspend

      or halt the virtual machine (complete VM shutdown, a little slower to restart):

      vagrant halt
    • To resume work on a VM that is suspended or halted:

      vagrant up
    • If you just want to restart the VM (same as halt/up), type:

      vagrant reload

      If you haven’t made any drastic changes to the build script, you should be able to just re-provision the VM. You can do this by using the --provision flag with either up or reload. This is will be faster than doing a full destroy/up, however depending on the changes you’ve done to the VM, could leave it potentially unstable. If the VM breaks, simply destroy/up as normal.

      NOTE: when resuming work, you may see this warning several times, default: Warning: Remote connection disconnect. Retrying.. . These warnings are not harmful and can be ignored.

  7. To completely delete the virtual machine (such as to start over from scratch with a fresh VM), type:

    vagrant destroy

    And if desired:

    vagrant up
  8. When the VM is “up”, you can go visit the homework submission website.

  9. When the VM is “up”, you can connect from your host computer to the virtual machine via ssh. Windows users will need to install SSH software (e.g., Cygwin or Putty). From a terminal in the repository directory type:

    vagrant ssh

    You will connect to the VM as user vagrant initially.

  10. The following additional users exist on the VM:

    user password
    vagrant vagrant
    root vagrant
    hsdbu hsdbu
    hwcgi hwcgi
    hwphp hwphp
    hwcron hwcron
    instructor instructor
    ta ta
    developer developer
    postgres postgres
    student student
  11. The VM has the following three courses by default and they are all part of semester f16:

    FIXME: This will change to “python course”, “c++ course”, “java course”, etc.

    • csci1000
    • csci1100
    • csci1200
    • csci2600
  12. Currently, there are four user accounts that can be used that have different permission levels within the system. Their password is the same as their username:

    • developer
    • instructor
    • ta
    • student
  13. Things that currently need to be done manually on Vagrant VM:

    • Setup SVN for one of the courses
    • Add users to the grading database for the courses
    • Add additional students to both the submission and grading areas
