    You misunderstand.

    The limitation is in the license agreement, not in the software. Regardless of edition, you can run as many VMs on any Hyper-V server as the hardware can handle.

    The license agreement states that you don't need to buy individual licenses for the VMs on DataCenter edition, but you do need them for the others. Again this is purely an accounting thing, there is no enforcement in the software.

    Since you're asking about how to activate it, you apparently don't care about no stinkin' agreements, install Standard or Enterprise on your host and be done with it.

    Hello,
    so your mean is if i install windows server 2008 r2 enterprise edition on host server then i can create for example 50 virtual machine with w2k8 r2 in my host and all of them can use host license right?

    there is no limitation that how many virtual machine with w2k8 r2 os can use host license?right?

    Thanks,

    I presume if you install a free linux distro, with each virtual machine on Hyper-V, no extra costs?

    But if you install W2K8 or W7, you need a licence per virtual machine.

    That's correct, you can create as many as you want. How many can run at a time depends on how powerful the hardware is.

    The licensing is completely separate and it's up to you to decide whether and how to comply.

    Well there are certain physical limitations to consider as well in regards to the type of Windows version you use for the host OS. Since we do alot of Hyper-V now for our organization and clients. For servers with 32 GB RAM or less you can use Windows Standard and Datacenter/Enterprise is used for any server that have more RAM than 32 GB. I just built a couple of 128 GB RAM Hyper-V servers for my company. Datacenter gives you unlimited guest virtual server licenses and the host license is based on physical CPU's installed. Enterprise gives you 4 guest server licenses. Of course this is if you want to play by the book. Otherwise you can run as many VM's as you want.

    Windows Standard will suffice in most instances, unless you have a mega server with more than 32 GB of RAM and need Enterprise to be able to allocate the additional resources. The other thing with such a large box to have Enterprise is to utilize the failover clustering with a SAN and this is what we're doing at my job.
