The Instant Clone Process from a Frozen Source
The process to create an instant clone from a frozen source virtual machine requires one-time initial preparation, but after that it proceeds faster than creating an instant clone from the current running point. The source virtual machine must be booted and running, in a state that you want to replicate to other virtual machines. VMware Tools must be installed and running in the guest operating system so that you can run the command to freeze the source virtual machine .
