IT Partners Conference – 6/2/2010 – Distributable Virtual Machines
Background of VMs at MIT
IS&T licensed VMware for MITDecember 2007
Thousands of staff & students at MIT started using VMware Workstation & Fusion
Departments started creating/using VMsDUSP IS&TSloanmore
Need a better VM for everyone
IT Partners Conference – 6/2/2010 – Distributable Virtual Machines
The Old Way – 2-8 hours
Create a VMInstall WindowsApply Patches, Reboot, more patches,
Reboot, even more patches (repeat)Install software and configureCopy VM files to new machinesHope settings are right
IT Partners Conference – 6/2/2010 – Distributable Virtual Machines
Downsides to the Old Way
Time consuming – 2-8 hours to createName conflicts
Windows SID collisions Problems adding to Windows domains
Windows machine name collisionsMAC Address conflicts
Identical user accounts (security risk)Everyone’s VM is a little bit differentSupport Nightmare
IT Partners Conference – 6/2/2010 – Distributable Virtual Machines
Goals for Doing things Differently
Save time and effortCreating VMInstalling & Configuring Software
Consistency (easier to support/troubleshoot)
Unique (accounts, SID, UUID & machine name)
Apply Best Practices including Security
IT Partners Conference – 6/2/2010 – Distributable Virtual Machines
Approach for creating distributable VMs
Lots of different needs identified by multiple groupsBase Windows VM (SWRT)Student VM (FSX & OEIT)Business Applications (Business Help Desk)Plus DLC VMs
Started several efforts until we discovered we were all working towards similar goals
Paused and brought the IS&T efforts together to provide a truly supportable and scalable Distributable Windows VM

The Future

Distributable Windows VM
Windows 7 - 32 bitBest Practices Security PolicyConfigured for MIT’s WAUS and patchedGeneralized (unique SID and other
identifiers)Targeted Audiences
Base VM for customizing by DLC (IT Partners)Student VM (students)Administrative Staff (faculty & staff)
IT Partners Conference – 6/2/2010 – Distributable Virtual Machines
Licensing for VM’s OS
Usage up to 4 Windows VM per machine covered under MSCA
Key Management Server (KMS) with Windows 7 makes this transparent for usersHas to be on MITnet (VPN counts) at least once
every 180 days
IT Partners Conference – 6/2/2010 – Distributable Virtual Machines
Base VM
Designed for Local Technical Experts to create custom DLC specific VMs
