Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD)* so called virtual machines or span class=systemdomU/spans* under a host operating system (span class=systemdom0/span).Using Xen you can separate your applications into different virtualmachines that are totally independent from each other (e.g. a virtualmachine for a mail server* a virtual machine for a high-traffic website* another virtual machine that serves your customers' web sites* avirtual machine for DNS* etc.)* but still use the same hardware. Thissaves money* and what is even more important* it's more secure. If thevirtual machine of your DNS server gets hacked* it has no effect onyour other virtual machines. Plus* you can move virtual machines fromone Xen server to the next one./p
