Xen.org Releases New Version Of Open Source Hypervisor
Xen.org, the developer of the open source Xen project, announced the release of the Xen 3.3 hypervisor engine, with new power-saving and security features.Xen, a virtual machine monitor for x86-compatible computers, draws on the contributions of more than 50 leading hardware, software and security vendors. For example, Imad Sousou, director of Intel's Open Source Technology Center, said, "At Intel, we continue to enable Xen to take advantage of the advancements in Intel Virtualization Technologies and other platform capabilities. Xen 3.3 is optimized for Intel's next generation micro-architecture Nehalem features; enhanced power management, performance, I/O and networking features for building flexible resource management solutions in an energy-efficient data center."
The new version also offers "CPU portability" to allow live relocation of virtual machines across different CPUs, as well as enhanced security features. The improved power management functions are an indication of work done to apply Xen to laptops and, eventually, smartphones.MacNewsWorld
