Virtual domain controller cloning is a new feature from Windows Server 2012 that I use because it's a very useful and simple way to add additional domain controllers to an Active Directory domain.

This feature requires that the hypervisor supports what Microsoft calls "VM-GenerationID". Hyper-V and ESXi do, but my client wants to use KVM exclusively as their hypervisor.

So my question is :

Does KVM support "VM-GenerationID", and therefore, fully support the virtual domain controller sloning feature in Windows Server 2012+?

I'd like to be absolutely sure on this point before suggesting this solution to my client. If so, from what version onward is this supported, and where can I find a real validation by KVM on this?

    It's such a trivially easy task to deploy a new Domain Controller, why don't you just deploy a new one? – joeqwerty Feb 23 '16 at 19:04
  • Because the proccess of "cloning" is event more ... secure, easier and faster ... than the old way – patmct Feb 26 '16 at 8:28

    It's more secure? How? In what way? Can you provide specifics? – joeqwerty Feb 26 '16 at 14:56

    This is really, really, really terrible. You're doing your client a large disservice by make design/architecture decisions based on what supports this feature. If you want to add a new domain controller, use the actual process that's been basically the same for 15 years. These days, it takes me about 5 minutes to create a new domain controller, an frankly, this new feature isn't faster, more secure, or easier, except in a very limited number of corner cases. – HopelessN00b Mar 2 '16 at 11:21

On KVM, VM-GenerationID support is currently a work in progress. It hopefully will be finished sometime in the next few months.
