Red Hat announces release of Enterprise Linux 5.5.

"In the fourth update to the Red Hat Enterprise Linux 5 platform, delivered in September 2009, Red Hat introduced the Kernel-based Virtual Machine (KVM) hypervisor alongside the Xen hypervisor. Today’s Red Hat Enterprise Linux 5.5 update provides a number of virtualization enhancements. Support for the large memory systems of new servers allows a larger number of virtual machines to be deployed on each physical server. With greater guest density customers have an opportunity to achieve higher levels of consolidation and reduce costs. Huge page support is now automatic and extended to virtual guests, improving the performance of memory-intensive applications. Support for Single Root I/O Virtualization (SR-IOV) offers virtual guests an improved ability to share PCI hardware resources and more efficient access I/O devices. As a result, Red Hat Enterprise Linux is one of the first operating systems designed to be capable of hosting a virtual guest that can saturate a 10 Gigabit Ethernet. Further I/O optimizations, which enable easier device reassignment, can help improve flexibility when migrating virtual guests across physical systems. In combination, these enhancements aim to allow large-scale, I/O bound, enterprise applications to be readily virtualized."
