Microsoft and XenSource 'Cooperate' for Linux Support in Windows Server

Microsoft announced this week it will cooperate with a leading Linux open source developer to provide interoperability between Windows Longhorn Server and Xen virtualization technology for Linux.

The company is working with Palo Alto, Calif.-based open source firm XenSource to deliver interoperability between Xen-enabled Linux distributions and Microsoft's coming hypervisor technology, which the company refers to as Windows Server virtualization.

Under the agreement, Xen-enabled Linux clients will be able to run on Windows Server virtualization, the two firms said in a statement. Xen is a popular hypervisor technology for Linux. According to statements on its Web site, XenSource was founded by the original Xen development team.

While Microsoft's hypervisor will ultimately be a component of Longhorn Server, it will not be delivered when Longhorn first ships. Currently, that is scheduled for late 2007 with the Windows hypervisor due within 180 days following that. Longhorn Server's Windows Server virtualization is set to enter beta late this year.

XenSource's XenEnterprise is planned for general availability as a packaged and commercially licensed product in the third quarter.
