Nesting a Hyper-V Server

[BoomAM]

Morning all,
For reasons that i cant be bothered going into, i have need of virtualizing a HyperV server, so that it can virtualize one HyperV VM (low spec).

There's various guides about that involve editing variables through SSH, but is it really needed? The guest VM doesn't have to work quick, just work.

Thoughts?

Thanks.

You need to run a Hyper-V server as a guest?

If that is the case, it wont happen. The hypervisor layer is not presented to the guests so you simply can't - try and start a gues inside a virtualised host and it'll complain the does not support virtualisation.

PistolPete is 100% correct here - if you install Server 2008 as a guest VM on Hyper-V, the guest OS will prevent you from adding the Hyper-V role.

Unless, of course, you're asking about nesting Hyper-V in VMWare vSphere/Workstation? If that's the case, then it's entirely possible. You do need to change some settings, but nothing to do with SSH as far as I can recall.

Perhaps you could furnish us with more information on what you'd like to achieve?

I know for a fact that with ESXi 5 you can run 2008 R2 running the Hyper-V role, running VMs within it. Xzibit would be proud.

This might possibly be the only time I would ever say this but... Maybe look at running Virtualbox in the 2008 R2 instance, to host the VM?

Both completely wrong.
Google "nesting hyper-V" and observe the millions of articles about it.
As long as the host hyper visor and every hyper visor in the theoretical chain is passing a specific CPU instruction, i forget the name, you can nest to as many level as you want.
I've read articles about people who have virtualized NT4 onto a 2008 host, which is virtualized onto a 2008R2 host which is clustered, which is virtulized onto a ESXi host, which is in VMWare Workstation.

Does it need to be hardware v8 to do that?

Can VirtualBox use HyperV VMs?

Okay. Find me one article that specifically discusses running Hyper-V on a guest VM that's running on a Hyper-V host. Do not link me to one about running Hyper-v on a guest VM that's running in vSphere, Workstation, Xen, VirtualBox etc. Then I will reluctantly accept your dismissive tone.

Edit: actually, don't bother trying to respond to my request because I already know for a fact that you cannot nest Hyper-V inside Hyper-V, so it's a waste of both of our time you even trying. Just install vSphere on the bare metal and then run your Hyper-V server on top of that. You can search for "nesting hyper-v" for instructions on how to do that - you'll observe millions of articles about it.

So your telling me to link to an article about nesting but not to link to one about nesting as you wont belive it?

Know for a fact? lol
If your not going to answer/help, then i would suggest leaving this thread and moving on as im not debating this with you.
You arn't being all that constructive and have gone all defensive when i have correctly pointed out that you can nest HyperV.

I think you need to re-read what he said.

Plus the OP only mentioned HyperV, so my comment is 100% correct.

Ive managed to find what i need and have adjusted the config on the ESX hosts accordingly.
Does anyone know if i need to create a new VM, or could i just modify the CPU code on an existing VM to allow HyperV installation?

If you've got the space, then a fresh VM is probably wiser.
Install shoudn't take much more than about 15 mins.

True, but i dont really have the resources to add an entire VM, ive got enough to put another 2Gb onto an existing VM though...

Decision had been made for you....
