Microsoft is also announcing that the next version of SCVMM will support the virtualization hypervisor available as part of Windows Server 2008 (codename “Viridian”), as well as select third-party virtualization software, including VMware and Xen. Customers use Microsoft’s System Center management tools to manage their Windows-based server and desktop environments, both physical and virtual. Customers also turn to Microsoft to manage cross platform. With the next version of SCVMM, customers will be able to manage, configure and optimize virtualized systems running VMware VI3 and Xen. Microsoft will update customers about these plans at the beta 1 milestone, which is scheduled for Q1 2008.
