Hyper-V Architecture 2016 and How To Install

@BBigford said in Hyper-V Architecture 2016 and How To Install:
If you don't apply a license to the host of the VMs, then there is the issue.
This part here is what I think you are mixing up. You apply datacenter licensing to the hardware, not the what is installed on the the hardware.
DC licensing doesn't care if it's XenServer, KVM or Hyper-V. It's there to license the VM's on that hardware. Nothing else is tied into it.
If you're saying you can't use DC licensing without the Dom0 being a Windows Server, you're sorely mistaken.

@FATeknollogee I believe it's required to run as an application, I don't think it has a web interface like XO.

For management sake, do we consider 5Nine the "XenCenter" equivalent for Hyper-V?
Yes
No "XOA" style manager AFAIK?
Not yet. Someone will make one, i'm sure.

That's correct.

Never tried it but here's a basic web interface.

I was just saying it would make sense to have a GUI install in that case.
The only reason you would ever install Windows Server on bare-metal instead of the free Hyper-V Server 2016, is if you need to use features or services on bare-metal that are not available or allowed on the free Hyper-V Server. For example, just because you CAN install something on Hyper-V Server, doesn't mean you technically are allowed to according to Microsoft's licensing.
For example, I have installed Windows Server 2016 Standard on a physical HOST because I needed to use deduplication on the host's physical storage. Deduplication is not available on Hyper-V Server 2016, so I was forced in to installing Windows. That's one scenario where you would not install Hyper-V Server.
But Scott is correct, you should otherwise ALWAYS install Hyper-V Server 2016 on bare-metal, regardless of licensing.

But, less than 13 Standard licenses and not growing (or installing more non-Windows servers as they grow), definitely stick with Core and license servers individually as needed.
Of course you already knew all of that, just thought it was worth mentioning here.
I don't understand how the VM licensing relates to Hyper-V.
Just using an example where someone might have more than 13 licenses of Windows Server on a host, using more than that would make sense to have a Datacenter license because the cost of DC would be less than the accumulative cost of Standard on each WS. Since a DC license can't be applied Hyper-V Server/free/non-licensed/Core/non-GUI.
I was just saying it would make sense to have a GUI install in that case.
DC isn't applied to Hyper-V at all. It's applied to Windows. There is no licensing for Hyper-V, so it's a different discussion. You are talking about the VMs, not the hypervisor.
I think what he might be getting at is automatic VM activation, which occurs if you have applied a Datacenter License key to Windows Server Datacenter running on the Host. But that's a moot reason to install full Windows on a Host when there are options to use a KMS or other license server.

Why would you need/want dedup at the hypervisor level? Are you implying that MS's dedup is not allowed to be used inside a VM? If so, do you have a link?

For example, just because you CAN install something on Hyper-V Server, doesn't mean you technically are allowed to according to Microsoft's licensing.
It's important to note though that you are allowed to install anything there as long as licensing for the feature is acquired. Example might be having Datacenter licensing for the hardware - you can then put any function or feature that you want in the Dom0 VM because you paid for it. It's still lean so many things won't exist or work. But you always have the option of paying for the Dom0 to be allowed to do additional things from Windows either by consuming one VM OSE from a standard license or by having a D.C. License.

I wonder if MS updated Hyper-V Server 2016 to allow you to add a DC key just for this reason?

Yes that's a good point.

SCDPM MBS, one example I'm actually doing.

Maybe I don't understand this question... but I'm running dedupe inside of a few different file server VMs just fine.
FileServer VM using a 5TB .vhdx for one of it's drives. And that is being deduped inside the VM.

Dedupe at the hypervisor level is important because of things like the OS. So there are exceptions, obviously. But let's say you have 100 VMs of CentOS 7 and 150 VMs of Windows 2016 and you keep them patched the same and have the same install images and setup... a good dedupe could in theory reduce 250 VMs OS portions down to just 10GB or so. That's an extreme example and nothing is that efficient, but you see how it could be effective in a way that "inside the VM" would not?

Yeah - I knew this answer as soon as I posted that. I guess MS is just limiting where that tech is available - i.e. licensed option.

Yes. You can still get dedupe in other ways, like by adding Starwind there or other storage technology. It's just that dedupe is not part of Hyper-V.
