Microsoft announced Viridian, it's Windows Server virtualization, has been delayed to the second half of the year.
Viridian is Microsoft's Windows hypervisor technology that will run beneath the operating system and manage resources for multiple virtual machines.
But Microsoft is way behind its Linux competitors on this front, as Red Hat and Novell's SUSE have both already integrated the Xen hypervisor technology into their server products.
"We still have some work to do to have the beta meet the 'scale up' bar we have set. Also, we're tuning Windows Server virtualization to run demanding enterprise IT workloads, even I/O intensive workloads, so performance is very important and we still have some work to do here," Mike Neil, the general manager for Microsoft's virtualization strategy, said April 12.
But Viridian is still scheduled to be available within 180 days of the release of Windows Server "Longhorn," which remains on track for beta 3 by the end of June 2007 and release to manufacturing in the second half of the year, he said.
Also delayed is the Windows Virtual Server 2005 R2 Service Pack 1, this update will now ship by the end of June.
