10. OBEY YOUR MASTER
• Build a master VM
• Includeall software you want
to share across clones.
• VMWare Tools

11. SEEK AND DESTROY
• Grab only the disk and prepare it:
• VMWare uses .vmdk (inside your master.vmwarevm)
• Fix the paths and remove the UUID
• VirtualBox uses .vdi
• Make disk files read-only and immutable

12. SPAWN OF THY MASTER
• Create a new VM
• Use the master disk image
instead of creating new
• Create a snapshot
• Run the clone
• May need to fix networking
strangeness

13. SIMPLES
• Lots of documentation online
