Microsoft Adopts Virtual Licenses
* * Beatles-Beatles is one of many to let us know that Microsoft has changed how they handle licensing for Windows Server and related products with regards to virtual machine environments. The new regiment will allow per-processor licensing to be handled based on the number of virtual processors rather than the number of physical processors in the computer.
This is true, but so is the opposite situation (which is probably more likely a situation).
If you have a four CPU server running 6 virtual OS's, if you only want SQL Server on one of those OS's you only need one copy, where as before if you wanted it on 1 you had to buy four copies.
Also check out his great series on running old games under Virtual PC.
/. is irrelevant.
More to the point you had to buy a 4 cpu licence for that single virtual server even though most virtual servers only virtualize a single processor and so you were paying the 4 cpu price for a 1cpu equivalent server.
To address the comment about dual core processors I am pretty darn sure I read in the past that Microsoft had adopted a policy of treating a single dual core processor as 1 cpu and not 2.

1) This change affects only virtual processors, not physical ones. If your running VMWare or MS Virtual Server than this is for you. Otherwise move along.
2)This licencing scheme is designed to save companies money instead of giving up more for MS. For example, say you have a 16 processor system, and you VMWare it so your running 4 instances of Windows Server 2003 with SQL server. under the old system, you had to buy SQL Server for all 16 Processors. Now you would only buy for the 4 VM's
3) Windows Server 2003 R2 Enterprise Edition is now licenced for 4 instances of itself per Machine. So you could run 4 Windows 2K3 Servers VM's on one server and MS says "go for it"

RTFA? It will reduce costs for most companies.
I RTFA, and here's my take on it:
If I have a 4 way box running 3 Windows VMs, I owe MS for 3 single CPU licenses (before I owed them for one 4 way license, more expensive).
If I have a 4 way box running 6 Windows VMs, I owe MS for 6 single CPU licenses (a 4 way license is cheaper than 6 singles)
According to TFA, you would never run more servers than CPUs in protection. That is utter bullcrap. ESX scales to 10 servers on a 2 way box according to VMware. I have a GSX box running on a 2 way box, and I have 6 production boxes using 25% of the CPU at any given time. That means I could scale to 15 with little trouble. In other words, this new scheme costs me more, a LOT more, than it did before.
So yeah, MS is screwing us. They're just either misinformed or hoping the readers are.
Once more for Mr. Leap-to-conclusion mat:
- This is a pay for what you use deal under virtualization, e.g. customers now buy fewer licenses in most scenarios
- Microsoft supports 1 license per physical CPU. The story is still somewhat inconsistent with Oracle, IBM, etc (try getting a straight answer from Oracle)
