Many software vendors now take virtualization into account with regard to licensing. Savvy organizations can get some significant cost savings out of virtualization-aware licensing.
Probably the best example of virtualization-aware licenses is Microsoft's policy for Windows Server If your host server runs Windows Server and Hyper-V and no other applications , you are entitled to a specific number of virtual instances of Windows Server , in accordance with your edition.

Beware license violations due to virtualization One oft-overlooked aspect of virtual server licensing is the effect that VM migration technologies, such as failover clustering and Microsoft live migration or VMware vMotion, have on licensing requirements.
Windows Server licenses are bound to the hardware. For example, if you purchase a Windows Server Datacenter Edition license , that license entitles you to run an unlimited number of Windows Server virtual instances on one physical server.

The more of a collective noise we all make, the louder it will collectively be heard hopefully by the powers at Microsoft.
