Hyper V Virtual Machine Activation Status

[rmuhammadali]

Dear All,

 

I have two machines with hyper-v installed on them. On hyperv1* system (running Server 2008 R2 Standard Edition) i have a virtual machine running DNS** with Server 2008 R2 Standard Edition. I need to move this running virtual machine on hyperv2 (running Server 2008 R2 Enterprise Edition).

 

The question is, when i move the virtual machine from hyperv1 to hyperv2 then, is there some problem with the license, which one is possible from the following options.

 

1) Still Activated with present license (on hyperv1)

2) Need to be Activated again (on hyperv2)

 

 

* I need to remove hyperv1 from the network

** DNS installed on hyperv1 is already activated and running fine.

 

Regards

RMA

There shouldn't be. I recently migrated a Win2008R2 Server Core DC/DNS Server from a Win2008 SP2 Enterprise Edition Hyper-V server to a Windows Server 2008 R2 SP1 Datacenter Edition Hyper-V server and had no issues whatsoever.

 

I exported the machine from hyperv1 and imported on hyperv2 and it fired right up.

Thanks for your response.

Another question is what if i just copied the virutal machine from hyperv1 to hyperv2 rather then exporting and importing.

Copying VHDs won't really work; you also need the entire Virtual Machine specification. Also if there are any snapshots or save files, that complicates it even more.

 

Yes, theoretically you can build a new virtual machine definition and attach the VHD to the VM; but if there are any inconsistencies between the new VM definition and the old, related to how the OS/Drivers are configured in the installation on that VHD, you may create instabilities or dysfunction in the new instance. Since we're talking about a critical infrastructure machine (a DNS Server), the most reliable methodology is to export the virtual machine and let the system do the work for you.
