Xen.org announced the release of a new version of the project’s open source hypervisor, Xen 3.3 today, with enhancements to security, performance and scalability.

The release is now available for download from the Xen.org community site and is the product of a distributed development effort by senior engineers from more than 50 hardware, software, and security vendors.

The new Xen 3.3 release provides users with the new features including:

* Power management in the hypervisor
* Hardware Virtual Machine (HVM) emulation domains for better scalability, performance and security
* Shadow pagetable improvements for the best HVM performance ever
* Hardware Assisted Paging enhancements
* Device passthrough enhancements
* CPUID feature levelling that allows safe domain migration across systems with different CPU models (within the same vendor brand – Intel or AMD)

Xen 3.3 provides virtualization for x64, IA64 and ARM-based platforms, and through close links with CPU and chipset vendors in the Xen project, Xen 3.3 also supports the latest hardware virtualization enhancements, like Intel Virtualization Technology (Intel-VT).

With Xen’s memory ballooning feature, the hypervisor can reallocate memory between guest Virtual Machines (VMs) to guarantee performance and allow greater density of VMs per server. Xen 3.3 also offers CPU portability to allow live migration of VMs across different CPUs, active power optimization to reduce server power consumption, and significant security enhancements.

Simon Crosby, CTO, Virtualization and Management Division, Citrix Systems, said in a statement, “In just two years, Xen has rapidly gained share in virtualization, much as Linux did in operating systems – and in the same period Xen has driven the price of competing hypervisors to zero, allowing any vendor to include virtualization for free.”

In addition to its growing development community, Xen hypervisor is the standard virtualization platform used by cloud computing providers like Amazon.com. It is also used in virtualization products from Citrix (XenServer), Fujitsu, Novell, Oracle (Oracle VM), Sun Microsystems (Sun xVM), and Virtual Iron, and is available as an embedded option in many x86 servers.
