Edit: I missed the significance of AVMA, but from a MS link I just read about it, it seems like you should be able to use it.

Yeah, it is a super weird thing that they do that the only situation in which this feature exists is a scenario where you'd never want it to exist. So people installing by best practice will never encounter it.

Thanks to you both for replying. What product key does one use with a DC license and hyper-V server on the guest Windows Server OS' then? One cannot re-use the DC product key AFAIK.

DC product key gets used on each VM, but not on the host. DC is reused standardly, that you don't need to enter it at all is purely an edge case that shouldn't even come up. All deployments of DC licensing assumes a reused key.

What is used is called a MAK key.

Yeah with AVMA, it requires the host to be running Windows Server Datacenter 2012 R2 or 2016 Datacenter. This is something you don't want to do in 99% cases, though, unless you have real business needs that require specific Datacenter-only features on bare-metal that are not available on Hyper-V Server.

AVMA should never alone be a reason to run Windows on bare-metal. That's just silly.

What if your Hypervisor was running VMWare or KVM and you have a Datacenter license? You wouldn't get AVMA then anyways on the VMs. It's not actually a benefit.

Funny, I do this on Server STD all of the time (utilizing the same serial for the two guest OS' regardless of hypervisor platform) but the two times that I've attempted it with DC the guests fail to activate. I always assumed it was a restriction with DC and that one has to use the full blown Windows installation with hyper-v role on this platform.

I only have 2 DC clients + 1 DC internal use license so I never investigated it further.

I guess I'm going down the rabbit hole of figuring out why this never worked for me.

Thank you.

You probably didn't get the MAK keys.

WOah Hyper-V is for free for real, i just downloaded it (2016) and toyed with it, cause of this video.... I always thought it is not

And yh downloaded from evaluation site but MS listed as unlimited, amazing video.

But after using it for the first time, its meh.. it opens cmd window + command line wizard, I wouldnt use it if starting from scatch it likes to be used from AD domain but you can use it without it domain via:

Step 1

Enable WinRM on both machines. This can be done trough an elevated command prompt. The command used for enabling WinRM is:

winrm quickconfig

Step 2

On the Hyper-V Management client open cmd.exe as administrator and add the server as a trusted hosts. Here you can comma separate to add multiple machines.

winrm set winrm/config/client @{TrustedHosts="192.168.1.15"}

Step 3

On the Hyper-V Management client add credentials to make the connection possible.

cmdkey /add:192.168.1.15 /user:ADMINISTRATOR /pass:**********

Its performance is okay, I managed it using Hyper-V manager in WIndows 10, and it feels very limited.

I loved that they kept notepad.exe and taskmgr.exe in the HyperV server, I can launch those and avoid Windows command line.

Notepad.exe --> File --> Open (GREATEST HACK EVER)

I dont know why GEN 2 cannot be installed from host CD/DVD rom, and GEN 1 can.

Also it is very difficult to share files or send files, like I am used with WinSCP or SFTP protocol with Linux and KVM, the sharing module is removed in HYPER-V I tried to share but was unable to, kept giving me errors.

Oh and they provide the hyper v integration as cab file (guest agent):
windows6.x-hypervintegrationservices-x64.cab

I cant belive I complained when VIRT IO Tools was repackaged some time ago and they changed some folders in there ISO image, while MS gives you a .cab file and not even an executable.

Also moving the VMs between 2 HYPERV needs FQDN

LOL, yup. Totally free. All features are included, no limits.

I've not tested by I can only assume that OpenSSH works fine on Hyper-V. Have you tested it?

What do you mean? Hyper-V Server isn't a file server.

But you can access anywhere on the server via admin share without issue... ex: \server\d$\share

What do you mean? What VM are you trying to install? You shouldn't need any integration tools at all for any modern operating system on a VM. They come built in and are updated via Windows Update (if running Windows OS)

If you install RHEL or CentOS, you can download a Linux Integration Services .ISO if you need to. You simply run the ./install.sh file. All other modern Linux OSs already have the Hyper-V Integration built in to the kernel.

Generation 2 only allows ISO
Generation 1 allows physical dvd drive and ISO

The ISO can be located on a physical CD. Just browse to it when selecting an ISO for your Gen2 VM.

In Gen1 VM Settings, you can select an image file or a physical CD/DVD drive.
In Gen2 VM Settings, you can select an image file only.

No to be honest, I was glad when the whole thing was over and I deleted my test environment which contained of 2 Hyper-V hosts
and 1 Windows 7 and 1 Centos 7

I felt Hyper-V was an afterthought attempt in the virtualization world, sorry if this offends people. but if you do you seriously have not used ESXi or KVM or XEN.
