Xen.org has made available an updated hypervisor that offers a better toolset as well as greater scalability and improved integration of third party security applications.

Xen 4.1 features, for instance, an XL toolstack and an enhanced scheduler for  "latency-sensitive workloads" and large systems.

On the scalability front, the update offers support for CPU pools for advanced partitioning and support for large systems including systems with more than 255 processors and 1GB/2MB super page support.

The open source hypervisor also offers a new memory access API to allow better integration of third party security solutions into Xen environments.

Xen is a leading virtualization hypervisor and the project is sponsored by XenSource owner Citrix.

Xen 4.1 was under development for 11 months. For more information, see the Xen.org blog on the update.
