Virtualization FAQs Does the Windows Server Datacenter

unlimited virtualization licensing just apply

to Microsoft virtualization? No. It applies to all virtualization products

including VMwares ESX Server


61/63

Virtualization FAQs

Were there any changes to thevirtualization licensing with WindowsServer 2008?

Yes. Windows Server 2008 Standard Editionnow provides support for running one activevirtual Windows instance.

Windows Server 2008 Standard Edition

One active VM

Windows Server 2008 Enterprise Edition

Up to four active VMs

Windows Server 2008 Datacenter Edition

Unlimited active VMs

Virtualization FAQs

How does licensing work with virtualizationwith products like SQL Server and BizTalkthat offer a per-processor licensing option?

When licensing in the per-processor model

you license for the number of virtualprocessors. However, for Enterprise Edition ifyou license all of the physical processors youcan run an unlimited number of virtual SQL

Server instances.http://www.microsoft.com/sqlserver/2008/en/us/l
