Clone VirtualBox Virtual Machine
How to easily clone or copy a VirtualBox virtual machine using your mouse and a wizard. Both the hard drive file and the machine xml file are cloned and new Universal Unique Identifiers are created. After the virtual machine is cloned the video continues with a demonstration of how to change the hostname or computer name of an Ubuntu desktop using the terminal. For an Ubuntu server you also have to edit the following file- " /etc/udev/rules.d/70-persistent-net.rules". because it has a cached version of the original VM's MAC address. Unfortunately this is not shown in the video. Comment out (or delete) the lines that deal with "eth0" and "eth1". When you reboot you should be able to get on the network and see that another "eth0" line has been added.
