Hyper-V Server clustering licensing requirements

I have a 2003 network with a file server/DC, an Exchange Server and a Terminal Server that I am planning to virtualize on HyperV Server 2008 R2 and host cluster. (Please note that I am talking specifically of host clustering throughout this post - I know about HyperV clustering as well but I am not interested in that avenue at this point.)  I have evaluated the hardware requirements of the servers I would need to be able to host the three VM's and also the SAN.  What I am not sure about is the licensing.  HyperV server is 'free' and as I have licenses for the 2003 servers I do not need any licenses there. It is my understanding however that I need for the purposes of host clustering to have the two HyperV nodes members of a domain. So does that mean I have to have a third computer that will act as the DC for the two HyperV servers - i.e. they will be members of that domain?  If that's the case what is the minimum OS I have to run on this third box?  From what I have read only 2008 Enterprise Server or DataCentre R2 supports clustering - Standard and Web do not.  So will I need to run 2008 Enterprise Server R2 on this third box?  Note that I am not planning to migrate from 2003 to 2008 any time soon so I have no need of 2008 server  - regular or Enterprise - at this time.  If this is the case the statement  that HyperV server is free and that it includes clustering is a bit misleading if the only way I can implement clustering is to get an Enterprise or Data Centre 2008 license and a computer to run it on.

From what i understand in a virtual environment the Virtual host requires an 2003 enterprise license which in turn allows you to run 4 instances of 2003 Standard as Virtual Servers on the host. 2 hosts would equal 2 enterprise licenses which would allow 8 Server 2003 instances on the 2 hosts. wether this applies to Hyper-V i am not sure but it is the model MS uses for other Virtual environments like VMWare and Citrix.

I would assume you need an enterprise licence for anything to do with clustering.

Sorry this does not answer all you queries but should give you a clearer understanding of the MS Model for server licensing in Virtual Environments.

Sorry but you did not read the question very closely. I specifically spoke about HyperV Server as the host. The information you gave me is completely off  track. I wasn't asking for general information about licensing. I was asking for very specific information - all the information you provided was something that I already knew - and in fact anybody Googling could have found out. Perhaps I should have been more specific about my knowledge but I would have thought that by reading my question closely someone would have known I was past the 'beginners' stage when it came to licensing. I posted the question on Experts because straightforward Googling was not getting me the answer.  I hope you don't mind but I I am going to close this question without awarding any points as I need somebody who is at the level where they have knowledge of the the very specific issue at hand.

why close the call because i misread your question. All questions are open to interpretation and in this case misinterpretation. If you do not like my response then simply state that it is not the answer you are looking for and wait for one that is. Someone with knowledge in your spwecific area will come along

Please notice that I asked if it was ok with you. You are welcome to say no and offer further answers. As far as leaving the question open for further answers my experience has been that once an answer has been posted by one Expert others tend to shy away and then I have to send an alert to the moderator asking the question be fanned out to other Experts. I try not to add to the moderator's workload if I can help it. In this situation it seemed the question could be closed and a moderator might be spared following up.

Hi,
http://www.microsoft.com/hyper-v-server/en/us/faq.aspx
Q.  Is Clustering and Live Migration included in Hyper-V Server 2008 R2?

A.  Yes. Hyper-V Server 2008 R2 includes live migration and host clustering and Hyper-V Server 2008 R2 will be available for free.


Hyper V Server R2 : Free
Clustering Hyper V Server R2: Feature of Hyper V Server R2 therefore Free
Requirement of AD is for Windows Clustering, you need a DC (WS2000, WS03, WS08, WS08 R2, any would do). This machine itself doesn't need to be enterprise or datacenter, it just needs to be DC.

Hope that helps.

Shahid

1) In all cases I will need another license as I only have licenses for the servers I'm virtualizing

2) Windows 2000 is not for sale, Windows 2003 even if for sale is more than 2008 last time I looked

3) So for cost effective purposes 2008 seems to be the way to go. However, 2008 standard doesn't support clustering, only 2008 Enterprise does. So does 2008 Standard have the same GUI setup for clustering  that comes with 2008 Enterprise even though it doesn't do it itself?

Thanks for the link.  However, I am not sure from it whether I need 2008 R2 Standard or 2008 R2 Enterprise to open up fully the clustering on the HyperV server. Do you  know for sure?

If you are asking if you can manage failover clusters using Windows Server 2008 R2 Standard? then the answer is yes you can since you have failover clustering mmc available in windows Server 2008 R2 std. I have managed failover cluster running Hyper V on Windows Server 2008 using Standard version of WS08. The only catch, as already mentioned was requirement of AD.
However, I personally have not managed Hyper V R2 cluster using Failover Cluster Manager either using WS08 R2 std or Ent, because I haven't had the chance to cluster Hyper V R2 Servers.

Hope that helps and sorry for delayed response.
