I'm not sure what you're asking. The 4 VMs from Enterprise means that the single license that you purchase allows for 1 physical installation plus installation of that license in 4VMs. 4 is not the limit of VMs that you can run in Hyper-V, it is just the limit that you can run without having to buy additional licenses.

You can run as many VMs as your resources (memory, CPU and disk space) on the host allows. The 4 VM count with Enterprise Edition means you get 4 windows licenses for free with the purchase of Enterprise Edition. You can buy additional licenses if you go over 4

If you're planning on running 12 vm's on one physical host , with no previous licensing, Datacenter Edition will probably be a better deal money-wise in the long run. Especially if those are going to be Enterprise versions that you want to run (Datacenter allows you to install any lower version of Server). It also allows you expansion in the future if you decide to upgrade hardware capacity. Hyper-V itself can run as many VM's as you have license for and that your hardware can support. You can also use existing Win client/server licenses if you're migrating those physical machines into the virtual space.

Unless you have some good raid / multiple hard drives, running 12 may be a IO problem!

That being said, there are no limitations to the number of VM's that you can run in Hyper-v

I believe that each licence of Enterprise gives you the ability to run 4 Enterprise guests. You may either buy 3 licences for what you want, or as you said, buy the data centre edition.

I know this has been answered, but want to record this...

Here's the URL you're looking for: Microsoft Hyper-V Server 2008 . Note the "Guest Virtualization Rights Included in Host Server License" row, where it states:

  • Each additional Windows guest VM requires a license.

So Enterprise means you get a license for the host, plus 4 additional VMs. If you need a fifth, you buy a liceneses for Windows Server.

I'm not sure if you can "stack" enterprise licensing - buying two enterprise licenses doesn't get you 8 VM licenses, I believe it gets you 1 host, 4 VMs plus one more Enterprise.
