What is VM CLONE?
A Clone in virtual Box is replica or copy of existing Virtual machine. Clone has same setting as the parent VM.
Advantage of Clone:
Clones are time saving products. Let say you have installed an XP machine on virtual box and also installed different software like GNS3, VMware etc. and now you want to make same copy of XP with same setting you can do this by virtual box clone feature very easy. Also for testing purposes you can make changing in clone and if something goes wrong you can create a new clone from parent VM and start working again from same point from where you have start testing.
Another example of clone is that you want to create and practice active directory, DNS, DHCP and ISA server on virtual box and you want to deploy these on individual VM. In such case you just install server OS on virtual box once and then create many clone from that server VM and you can save much time and efforts.
Making Clone in Virtual Box:
Creating clone in virtual box is a very easy job. Just open the virtual box and select the virtual machine for clone. Open “machine tab” and then click on clone.
Set the clone name and click on next.
