# VBoxManage clonehd /Vbox/oldxp.vdi /Vbox/newxp.vdi
6.Change UUID of VDI Dusk
=======================
C:\ > VBoxManage internalcommands sethduuid "C:\Users\Name\VirtualBox VMs\Example\Example.vdi" --- Windows
# VBoxManage internalcommands setvdiuuid /path/to/virtualdisk.vdi --- LInux
7.To start a VM during startup
============================
Add entry to "/etc/rc.local" as follows and restart the system
# vi /etc/rc.local
..
su - (username) -c "VBoxHeadless --startvm (OS-Name) &"su - adminad -c "VBoxHeadless --startvm UB12-x64-L300 &"
