According to IT Week, “The updated system includes version 3.0.3 of the open-source Xen virtualization software, which was originally scheduled for release early in July.”Roger Klorese, product director at XenSource, told IT Week, “We decided to synchronize the release of 3.0.3 with the Fedora Core 6 schedule and hence push it back… It now has several of the features that were originally slated for 3.0.4.” XenSource had previously said that most of the changes in the 3.0.3 release would affect Xen’s para-virtualization capabilities. This update includes optimizations for para-virtualized USB and network performance, as well as a para-virtualized frame buffer that enables graphic displays of virtual machines. Other new features may include a new CPU scheduler and support for a basic NUMA memory allocator. Klorese told IT Week that the 3.0.4 release is expected before Christmas. He said that 3.0.4 would be optimized to run on servers that were fitted with four CPUs, which is what they expect most customers will be using, although Xen supports configurations with 32 CPUs.
