With Windows Server standard edition, you would indeed pay for each Windows guest that ran on Intel virtualization including VMware, Xen, Virtual Server, or Hyper-V. If a customer licenses Windows Server Enterprise Edition (EE) to a host server, that license will support from 1-4 guest Windows Server guests with 5-8 requiring another EE license, etc. If you choose to license Data Center edition to that same host, you would be allowed unlimited Windows Server guests on that server.

Is this really true??? One per *virtual*, not *real*, machine? If I were two run two copies of Windows on *one* PC, using e.g. VM-Ware, I would be required to pay twice??? Just wondering, and surprised, Shimon
