Xen Hypervisor 4.2.1 Download

+

Welcome to the Xen 4.2.1 download page! +

+ +

Xen 4.2.1 is a maintenance release in the 4.2 series and contains:

+
    +
  • TODO: add items here
    • +
+ +

The Xen 4.2 release contains a number of important new features and updates including:

+ +

The release incorporates many new features and improvements to existing features. There are improvements + across the board including to Security, Scalability, Performance and Documentation.

    + +
  • XL is now the default toolstack: Significant effort has gone in to the XL + tool toolstack in this release and it is now feature complete and robust enough that we have made + it the default. This toolstack can now replace xend in the majority of deployments, + see XL vs Xend Feature Comparison. + As well as improving XL the underlying libxl library has been significantly improved and supports + the majority of the most common toolstack features. In addition the API has been declared stable + which should make it even easier for external toolstack such as libvirt + and XCP's xapi to make full use of this functionality + in the future.
    • + +
  • Large Systems: Following on from the improvements made in 4.1 Xen now supports even + larger systems, with up to 4095 host CPUs and up to 512 guest CPUs. In addition toolstack feature like the + ability to automatically create a CPUPOOL per NUMA node and more intelligent placement of guest VCPUs on + NUMA nodes have further improved the Xen experience on large systems. Other new features, such as multiple + PCI segment support have also made a positive impact on such systems.
    • + +
  • Improved security: The XSM/Flask subsystem has seen several enhancements, including + improved support for disaggregated systems and a rewritten example policy which is clearer and simpler to + modify to suit local requirements.
    • + +
  • Documentation: The Xen documentation has been much improved, both the + in-tree documentation and the wiki. + This is in no small part down to the success of the Xen Document Days so + thanks to all who have taken part.
    • + +

+

You can find more information in the Xen 4.2 release notes, + the Xen 4.2 feature list and the + Also see the Xen 4.x Feature Matrix.
