Virtual Box - Cloning Drives

Prerequisite for Fedora 10
dkms package

Cloning

NB: Windows Users will call this copying.

Cloning allows u to use an existing installation as the basis of another installation/config.
For example u can clone the Virtual HDD of a Solaris appliance so that u can have another solaris appliance with Glassfish on top.

Command
#VBoxManage clonevdi soure.vdi target.vdi

The target.vdi will be created when u run the command. If a Virtual HDD exists with the same name the command will fail with an error.
