The open-source Xen virtualization hypervisor project is out today with a major milestone update providing improved performance and enhanced security features. The Xen Project is managed as a Linux Foundation Collaboration project initiative and has multiple stakeholders, including Intel, Citrix, Amazon and Rackspace.
Among the new features in the Xen 4.5 update are capabilities aimed at reducing the impact of the so-called “noisy neighbor” issue in multitenant cloud and data center environments.
