"There is an immense number of virtualization improvements and features in this release," Fedora Project Leader Paul Frields told InternetNews.com. "These things will affect anyone using virtualization across the board." Virtualization has been a big push this year for Linux vendor Red Hat (NYSE: RHT). It's also a big area of focus for the Red Hat-sponsored Fedora Linux 12 release, which is due out next week. The Fedora Linux distribution has been including virtualization technologies beginning with the Fedora Core 5 release in 2006 and has been steadily adding new virtualization features ever since. In Fedora 12, the open source Linux community project is adding new technology to improve virtualization memory management and performance.
