Exclusive: Xen Grows Up
|
|
In the past year, development of the open source Xen virtualization platform (http://www.cl.cam.ac.uk/netos/xen/) has forged ahead at a rapid pace, adding support for hardware virtualization and large- scale enterprise server hardware such as symmetric multiprocessor (SMP) guests and physical address extensions (PAE). Simultaneously, the Xen project has amassed a substantial community of developers and refined the software to be stable and robust. Now with a third major release, Xen is ready for “The Big Show,” production use. Up until the recent release of Xen 3.0, a major obstacle to the adoption of Xen in some environments was the software’s lack of support for unmodified operating systems. Xen’s original approach of paravirtualization, modifying an operating system to facilitate virtualization, yielded great performance, but failed to host operating systems for which source code is unavailable.
