Overview

Microsoft provides virtual machine disk images to facilitate website testing in multiple versions of IE, regardless of the host operating system. Unfortunately, setting these virtual machines up without Microsoft's VirtualPC can be extremely difficult. The ievms scripts aim to facilitate that process using VirtualBox on Linux or OS X. With a single command, you can have IE6, IE7, IE8, IE9 and IE10 running in separate virtual machines.

NOTE: As of Feb. 1st, 2013, the MS images are fully compatible with Virtualbox, thanks to the modern.IE project.

Quickstart

Just paste this into a terminal: curl -s https://raw.github.com/xdissent/ievms/master/ievms.sh | bash

Requirements

• VirtualBox (http://virtualbox.org)
• Curl (Ubuntu: sudo apt-get install curl)
• Linux Only: unar (Ubuntu: sudo apt-get install unar)
• Patience

Disk requirements

A full ievms install will require approximately 37G:

Servo:.ievms xdissent$ du -ch *
5.7G  IE10 - Win8-disk1.vmdk
2.6G  IE10 - Win8.ova
2.5G  IE10_Win8.zip
1.5G  IE6 - WinXP-disk1.vmdk
724M  IE6 - WinXP.ova
717M  IE6_WinXP.zip
1.6G  IE7 - WinXP-disk1.vmdk
 15M  IE7-WindowsXP-x86-enu.exe
1.6G  IE8 - WinXP-disk1.vmdk
 16M  IE8-WindowsXP-x86-ENU.exe
 10G  IE9 - Win7-disk1.vmdk
4.7G  IE9 - Win7.ova
4.7G  IE9_Win7.zip
3.4M  ievms-control.iso
4.6M  lsar
4.5M  unar
4.1M  unar1.5.zip
 37G  total

You may remove all files except *.vmdk after installation and they will be re-downloaded if ievms is run again in the future:

$ find ~/.ievms -type f ! -name "*.vmdk" -exec rm {} \;

If all installation related files are removed, around 21G is required:

Servo:.ievms xdissent$ du -ch *
5.7G  IE10 - Win8-disk1.vmdk
1.5G  IE6 - WinXP-disk1.vmdk
1.6G  IE7 - WinXP-disk1.vmdk
1.6G  IE8 - WinXP-disk1.vmdk
 10G  IE9 - Win7-disk1.vmdk
 21G  total

Bandwidth requirements

A full installation will download roughly 7.5G of data.

NOTE: Reusing the XP VM for IE7 and IE8 (the default) saves an incredible amount of space and bandwidth. If it is disabled (REUSE_XP=no) the disk space required climbs to 74G (39G if cleaned post-install) and around 17G will be downloaded.

Installation

1. Install VirtualBox (make sure command line utilities are selected and installed).

2. Download and unpack ievms:

   • Install IE versions 6, 7, 8, 9 and 10.

     curl -s https://raw.github.com/xdissent/ievms/master/ievms.sh | bash

   • Install specific IE versions (IE7 and IE9 only for example):

     curl -s https://raw.github.com/xdissent/ievms/master/ievms.sh | IEVMS_VERSIONS="7 9" bash

3. Launch Virtual Box.

4. Choose ievms image from Virtual Box.

The OVA images are massive and can take hours or tens of minutes to download, depending on the speed of your internet connection. You might want to start the install and then go catch a movie, or maybe dinner, or both.

Recovering from a failed installation

Each version is installed into ~/.ievms/ (or INSTALL_PATH). If the installation fails for any reason (corrupted download, for instance), delete the appropriate ZIP/ova file and rerun the install.

If nothing else, you can delete ~/.ievms (or INSTALL_PATH) and rerun the install.

Specifying the install path

To specify where the VMs are installed, use the INSTALL_PATH variable:

curl -s https://raw.github.com/xdissent/ievms/master/ievms.sh | INSTALL_PATH="/Path/to/.ievms" bash

Passing additional options to curl

The curl command is passed any options present in the CURL_OPTS environment variable. For example, you can set a download speed limit:

curl -s https://raw.github.com/xdissent/ievms/master/ievms.sh | CURL_OPTS="--limit-rate 50k" bash

Features

Clean Snapshot

A snapshot is automatically taken upon install, allowing rollback to the pristine virtual environment configuration. Anything can go wrong in Windows and rather than having to worry about maintaining a stable VM, you can simply revert to the clean snapshot to reset your VM to the initial state.

Resuming Downloads

If one of the comically large files fails to download, the curl command used will automatically attempt to resume where it left off. Unfortunately, the modern.IE download servers do not support resume.

Reusing XP VMs

IE7 and IE8 ship from MS on Vista and Win7 respectively. Both of these images are far larger than the IE6 XP image, which also technically supports IE7 and IE8. To save bandwidth, space and time, ievms will will reuse (duplicate) the IE6 XP VM image for both. Virtualbox guest control is used to run the appropriate IE installer within the VM. The clean snapshot includes the updated browser version.

NOTE: If you'd like to disable XP VM reuse for IE7 and IE8, set the environment variable REUSE_XP to anything other than yes:

curl -s https://raw.github.com/xdissent/ievms/master/ievms.sh | REUSE_XP="no" bash

Control ISO

Microsoft's XP image uses a blank password for the IEUser, which disallows control via Virtualbox's guest control by default. Changing a value in the Windows registry enables guest control, but requires accessing the VM's hard drive. A solution is to boot the VM with a special boot CD image which attaches the hard disk and edits the registry. A custom linux build has been created based on the ntpasswd bootdisk which makes the required registry edits and simply powers off the machine. The ievms script may then use Virtualbox guest controls to manage the VM.

The control ISO is built within a Vagrant Ubuntu VM. If you'd like to build it yourself, clone the ievms repository, install Vagrant and run vagrant up. The base ntpasswd boot disk will be downloaded, unpacked and customized within the Vagrant VM. A custom linux kernel is cross-compiled for the image as well.
