Deployment Hyper-V Environment with SCVMM 2008

Hi everyone,

Currently I have an environment which has VMware running. It consists of 1 domain (company.local) for our whole environment. I wanted to make the switch to Hyper-V and would be using SCVMM to do the migration. I have experimented a little bit with SCVMM and one of the prerequirements was that it needed to be installed on a domain controller.

I wanted to have one host which would be hosting the virtual machines.
If I want to install SCVMM on this host, it needs to be a domain controller.

Now is my question: Do I need to make a second domain just for this host?

So basically:

Hyper-V Server (Host)
     - VM (company.local)
     - VM (company.local)
     - VM (company.local)
     - ...   (company.local)

Should my host be part of this domain or should I make a domain (virtualisation.local) on this hyper-v server host?

There is no such requirement. You can install SCVMM on any domain member server. However, the Hyper-V host needs to be part of the domain in order to be managed by SCVMM.

Oh sorry, my bad, you are right.
My question is then: Should I make the host computer part of the company.local domain or create a new domain?

The best practices suggest that you have a separated domain for all management stuff. However, it could be part of the primary domain. If that’s the case you need to be sure that you have at least one domain controller that is not on a virtual server managed by the same SCVMM.

If you want to protect your Hyper-V servers better you could create a dedicated domain for that.

If I were you I would put all my Hyper-V servers with the SCVMM (physical) server on dedicated subnet and create a dedicated domain. I would also make my SCVMM a DC – however, it is not possible to promote a SCVMM to a DC without uninstalling the SCVMM first, so it should be done before. But, I am a little bit paranoid about security…    

So, it’s your choice of the desing

Thanks for your sugestions, spaperov. The thing is that we only would be having 1 hyper-v server. We would be using SCVMM to do the migration from vmware to hyper-v. In the future, maybe we would be implementing another hyper-v server.

So you would recommond the following set-up
1 DC hyper-v Server (domain: virtualization.local) 192.168.10.0 /24
       - VM 1, 2, 3, 4, ... (domain: company.local) 192.168.11.0 /24

Maybe a stupid question: but then I always would need to change my ip-settings if I want to login into the hyper-v server remotely?

To manage the Hyper-V server from company.local you will need to configure two things:
-      Routing between 192.168.10.0 and 192.168.11.0
-      Domain trust between company.local and virtualization.local

If you allow me to ask: way do you want to manage one server with SCVMM? We have 3 Hyper-V servers and I do not use SCVMM to manage them. My servers are not in a domain, they are located on dedicated IP subnet as stand-alone servers in a workgroup. I am managing them from my laptop connected to the primary subnet or through VPN and from a management station that has 2 NICs: one in the primary subnet and one in the management subnet. Both, the laptop and the management station are in the domain. I am using RSAT for Windows 7 that includes Hyper-V Manager to manage the servers (because the servers are not in the domain, it requires a small additional configuration with hvremote.wsf: http://archive.msdn.microsoft.com/HVRemote).

I’ve tested SCVMM in my lap and I decided to save the money on it for better hardware.

To convert VMWare to Hyper-V disks you could use third-party free software, for example http://www.starwindsoftware.com/converter

I was thinking of using 2 NICs on the management pc (only SVCMM and DC of the domain virtualization.local) to access the machine. Is this also possible without having to make a trust between the domains?

The main reason why to use it is maybe a bit arrogant, but just because we can. Apparently we can use this license for free by microsoft. This is also why we are going to shift from VMware to Hyper-V. The licenses of microsoft are free so we save the money of vmware. The reason why I wanted to use this is to test this kind of software and also to help me in doing the migration from vmWare to Hyper-V.

Does SVCMM support live migration from vmware to hyper-v without the servers having to go down?

Thansk again spaperov!!

You need trust if you want to manage a host in virtualization.local from company.local. If you are going to do just RDP to a server in in virtualization.local, you don’t need it. The other option is to try the script I provided you as if the server is in domain and the management station is in workgroup – this could work and save you from the trust stuff.  

SCVMM is not a free product; however you could have an evaluation copy from Microsoft.

Microsoft Hyper-V is a free product but it doesn’t have a GUI, so you should master PowerShell. You could however use Hyper-V manager from RSAT for Windows 7 to manage it and, may be, you can use SCVMM too.

I am not aware if SCVMM supports live migration from vmWare.

Another point that you should be aware of, is that migration of domain controllers is not supported. You need to promote a new and demote the old one.

Was planning to do RDP only if I would work with the 2 domains, but the workgroup thing is something I really like actually, however in that scenario there is no support for SCVMM.

I know that SCVMM is a paid product, but my company has an agreement with microsoft that we can use this license for free. Something to do with our microsoft partnership if I am correct.

I would be using Windows 2008 Server R2 with hyper-v role or maybe the core-installation. Thinking of using core-installation for less overhead and then managing with RSAT or the SCVMM.

I don't understand what you mean with the demoting and promotion of the domain controller. Could you maybe explain what would be the steps in migrating a domain controller from vmware to hyper-v?

Thanks again for your help, great help and much appreciated!

No, the workgroup scenario is not supported by SCVMM.

I’ve never migrated domain controllers so, I cannot help with the steps. About my point: I have run on some internet and EE posts that say that it could be a problem with unique ID of the virtual machine if we are using export/import feature.

For more information http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv%28WS.10%29.aspx see the section “Virtualization deployment practices to avoid”. I know that P2V migration of DC is possible, but I cannot say about V2V migration.

Thanks for the information spaperov, Will look into it!

I will start testing the v2v scenario's first before I do it for real.

Thank again!
