What are the benefits of a Xen VPS?
Xen virtualization offers a more complete standalone guest operating system compared to OS-level virtualization such as FreeBSD Jails. Xen virtualization makes use of Intel’s Virtualization Technology to present a virtualized physical computer to the FreeBSD guest operating system. This allows some features that are not available in a FreeBSD Jail, since the Xen VPS has its own separate kernel. The main benefits available in a Xen VPS are advanced networking features such as firewalling, tunnelling and additional IP addresses. You can also modify and build your own kernel in a Xen VPS.
