un extrait de l'article :

In early December, one of our clients was on Microsoft’s web site and read “Your Ultimate Quick Reference Resource for Licensing and Pricing.” The guide summarizes OS and application licensing scenarios in a relatively brief 39 pages (compared to the 104 page Product Use Rights, which has served as the definitive reference for Microsoft licensing policy).

Now back to the problem. On page 11 of “Your Ultimate Quick Reference Resource for Licensing and Pricing” there is a FAQ with the following question and answer:

Q: If I move an instance of Windows 2003 to run as a virtual instance on
a server with Windows Server 2008 Enterprise running in the physical
operating system environment. Can I use Windows Server 2003 CALs to
access the virtual instance of Windows Server 2003?

A: No. Because the virtual instance of Windows Server 2003 runs on a
Windows Server 2008 license, the user or device accessing the virtual
instance of Windows Server 2003 needs a Windows Server 2008 CAL.

Un article intéressant qui pointe le possible futur changement de droit de licence Microsoft...
