Windows Server 2019 on Hyper-V 2016

Now finally Microsoft have updated the misleading documentation on supported guest os within Hyper-V. This is quite important as some people tend to get stuck on small details and as my good friend Didier wrote on his blog, Hyper-V supports guest OS n+1, although that now gets a bit altered with the semi-anual releases.

Now the docs page is updated and shows the following:

Automatic VM activation heads-up!

There is though a small or big thing that needs to be considered if you have an environment with Hyper-V servers and utilize the AVMA. If you plan to deploy Server 2019 guest VM´s there is no way to get them auto activated on a 2016 Hyper-V host.

If you are a bit more old fashioned and utilize a KMS you will just need a KMS server that is newer than 2012 as the key for 2019 needs the KMS to be hosted on at least a 2012R2 Windows Server!

Upgrading my homelab to Server 2019

My homelab environment consists of two Intel NUC and I have been playing around with the insiders previews of Server 2019 on one of them and the other one was running Server 2016.

As you might know there is a bit of a hustle of the nic drivers with the server versions of Windows and the Intel NUC´s so there are some steps to get it working. I had some issues where the nic failed during in-place upgrade between preview versions of 2019 and as I do not have a KVM I had to move the NUC to a monitor and fix it. To get the drivers in I had to set the server into test mode:

After I did this and rebooted the server I could update the nic drivers that I already had modified as per this blog post.

I wanted to test and update my 2016 server with an in-place upgrade without moving it from the closet and as a precaution I changed to test mode first and then started the update…

After the upgrade went through successfully I changed back to non-test-mode:

I had a small issue with the Windows Update after the upgrade and it would not finish installing the CU of 2018-12… As a mitigation if this I went for the command line tool of System File Checker, SFC and the parameter /Scannow I also did a Dism repair and after these two successfully ran I could continue with the Windows Update!

Happy NUC-playing with 2019 🙂

Announcing the Windows Server Summit 26 of June
