I set up Server 2016 TP3 without gui.
Tried to install Hyper-V feature and got a message:
install-windowsfeature : A prerequisite check for the Hyper-V feature failed.
- Hyper-V cannot be installed: The processor does not support second level address translation (SLAT).
At line:1 char:1
- install-windowsfeature hyper-v -restart
I installed 2016 on my test box on which I wiped out Server 2012 R2 running Hyper-v.
The machine is Quad Core.
I believe that Hyper-V of 2012 required SLAT... because could not install Hyper-on on laptop running Windows 8.1 (and the message was about no SLAT).

Hyper-V Server 2012 didn't require SLAT, But Windows 8.x Hyper-V did.
Now, all the server version does too.
If you have a Core 2 Quad core, you don't have SLAT.

Hyper-V 2012 R2 did not require SLAT / EPT. Windows 8.1 did.
Wdinows 10 / Server 2016 requires it (there is no way around the requirement).
Run coreinfo.exe with the -v swtich to see if your system supports it.

You should still be able to install nano on bare metal.
Just cannot add Hyper-V to nano.

I was ready to put my both labs machines into the garbage...
But just got an idea that I can install back 2012 and test 2016 and it's NANO.
Wanted to see NANO on bare metall...
Thanks!

sure... 2016 is installed without any problem. it is Hyper-V part that needs SLAT.
and Hyper-V in Nano should be cool...
