You can install and run as many virtual machines as you like – the only practical limits are disk space and memory. VirtualBox is deceptively simple yet also very powerful. It can run everywhere from small and forward in virtual machine time. You can delete snapshots while a VM is running to reclaim disk space. • Infrastructure consolidation. Virtualization can significantly reduce hardware and elec- tricity your VM. There are many and potentially complicated ways in which VirtualBox can provide hard disk space to a VM (see chapter 5, Virtual storage, page 79 for details), but the most common way is to use a
