Cloning a disk is an Unix-y type way of creating a duplicate disk. We need to invoke the CloneHd command of the VBoxManage tool, supplying the disk to clone and the name of the new ‘cloned’ disk. In its simplest form, you would do something like this at the command-line:
VBoxManage clonehd "DiskToClone.vdi" "ClonedDisk.vdi"
The VBoxManage tool will clone the disk for you, and creating a new UUID in the process.
Start a cmd box and go to the directory “C:\Program Files\Oracle\VirtualBox”
Then execute [VBoxManage clonehd "F:\vmware\RAC1\node_rac1.vdi" "F:\vmware\RAC2\node_rac1.vdi"]
C:\Program Files\Oracle\VirtualBox>VBoxManage clonehd "F:\vmware\RAC1\node_rac1.vdi" "F:\vmware\RAC2\node_rac1.vdi" C:\Program Files\Oracle\VirtualBox>VBoxManage clonehd "F:\vmware\RAC1\node_rac1.vdi" "F:\vmware\RAC2\node_rac2.vdi" Oracle VM VirtualBox Command Line Management Interface Version 3.2.0(C) 2005-2010 Oracle Corporation All rights reserved. 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Clone hard disk created in format 'VDI'. UUID: 738b60bc-98e0-4380-b179-d3d8b3abd7e4 C:\Program Files\Oracle\VirtualBox>
The cloned disk can now be used on a new VM
