Abstract
Redo logs are used to facilitate efficient cloning of virtual machines. When a virtual machine with a virtual hard disk is to be cloned, two redo logs are created, both of which are linked to the virtual hard disk. The virtual machine being cloned is then linked to one redo log, and a newly created virtual machine is linked to the other. Each time an additional virtual machine is created, two new redo logs are created and linked to the end of the disk chain. The parent and newly created virtual machine are each linked to one of the new redo logs.
