I understand that a single Windows Server 2008 R2 Enterprise Edition license includes 4 free guest virtual machines using Hyper-V. Suppose I do that, and have 4 VMs running, but then want to expand.

If I separately purchase additional Windows licenses, or I consolidate a machine with an existing license, can I spin up a 5th, 6th virtual machine (presuming there are enough CPU/RAM resources on the host)? Or does the host OS limit the number of virtual machines allowed?

There is no technical limitation on the number of Virtual Machines you can host.

However, I believe that the licence permits 4 Virtual copies per physical copy installed not per licence.

...On top of this, surely, you would still be entitled to install as many copies as you like if you purchased a Windows Server licence for each extra instance. That being said, You may want to take a look at Datacenter edition - which entitles you to use as many instances of Windows as you want.

I do not think Microsoft would punish or try to sue you if you tried and had paid for a copy, however, I think it is breaking the terms.

IANAL
