Hall A & C Analysis Workshop June 26-27, 2017
Virtual Machine Image

IMPORTANT: If you are coming to the workshop in person,
there is NO NEED to download this large image. We will distribute
an exact copy of it on USB drives at the beginning of the workshop.
This download is provided specifically for remote participants.

Installation
~~~~~~~~~~~~
1) Ensure that you have VirtualBox running on your system.
   See https://www.virtualbox.org for details.

   Please install VirtualBox 5.1 or higher. Version 4.x will
   definitely not work, and 5.0 is untested. On Linux, be
   careful to check the version that your distribution repository
   provides. Those versions are often old. In that case, do not
   install from the repository, but download a matching package from
   the VirtualBox web site instead. Be sure to get the 64-bit version
   of VirtualBox.

   You'll need a 64-bit computer with at least 4 GB of memory.
   Minimum OS requirements are Windows 7 or Mac OSX 10.9.
   Requirements for Linux vary, but Fedora 22+, Ubuntu 14.04+ and RHEL7
   should definitely work.

2) Download the archive file CentOS_7_VM.tar.xz (6.6 GB)
   as well as the .sha1 checksum file. (Get the .asc signature file
   too if you are paranoid. Exercise: verify the signature ;)

3) Verify the integrity of the archive
   sha1sum -c CentOS_7_VM.tar.xz.sha1
   This should report "OK"

4) Unpack the archive in a convenient location, such as the VirtualBox
   default directory. You'll need at least 20 GB of space, better 30 GB.

   On Linux, just type
   tar xvf CentOS_7_VM.tar.xz

   On Mac, you might need to install "xz" from Homebrew or otherwise
   before using the tar command above.

   On Windows, you can use 7-zip or WinRAR (free trial), for example.

5) (Double-)Click on the .vbox file in your file manager, or add
   this machine to VirtualBox via the GUI (Machine->Add...)

6) If your computer has more than 4 GB of RAM, you might want to
   increase the RAM available to the guest OS. In the VirtualBox
   GUI, click on Settings->System. Move the slider next to "Base Memory"
   to the desired amount. You don't need to go beyond 4 GB.

Running
~~~~~~~

1) Click the green "Start" button in the GUI. The guest OS should start up.

2) You'll be greeted with a login screen for "Workshop Participant".
   The password was sent in earlier emails. The account name is "me".
   You can sudo from this account if necessary, for example to install
   additional packages.

Toubleshooting
~~~~~~~~~~~~~~
- If you get a message about "VT-x disabled" or similar, you need to enable
  the "Virtualization Extensions" in your computer's BIOS. This is
  harmless, but changing BIOS settings can be risky unless you know
  what you are doing. The only change you should make is to enable
  "VT-x" and "VT-d" (if available). These setting might have various
  other, similar names, depending on your computer's BIOS.

- On Linux, odd errors about "kernel modules" usually mean that your
  VirtualBox installation is damaged or incorrect. Try cleaning everything
  out, and reinstall.

Please contact me with any questions.
