XenSource Licenses Microsoft's VHD As Format War Begins

XenSource has licensed Microsoft's Virtual Hard Disk (VHD) format for its upcoming Xen 3.0-based virtualization server, called XenEnterprise.

As LinuxWorld Expo and Open Solutions World kick off in Boston, XenSource announced the deal with Microsoft and formally launched XenEnterprise, which is slated to begin shipping in the second half. XenSource is the Palo Alto, Calif.-based commercial spinoff of the Xen open-source project.

Meanwhile, virtualization market leader VMware stoked the fires by announcing Monday availability of its own virtual disk format specification at no cost.

For XenSource customers, supporting Microsoft's VHD format will enable XenEnterprise to run high-performance Windows guest workloads on Xen 3.0, according to XenSource. XenEnterprise will virtualize Windows, Linux and other operating systems in production environments and offer built-in physical-to-virtual tools, the company said.

The deal illustrates the increasing “co-opetition” and competition in the virtualization software market.
