Re: Install windows server 2016 on a VM
"The OEM license isn't intended to be used as a VM"
No, that's not accurate. I think you mean PRODUCT KEY, not license ... they aren't the same thing. Assuming you have Standard or Datacenter, if you can't activate the VM using the PK that comes with the server, you can use ANY key to activate it. The key you use is only used for activation, not to license the machine. The VM is licensed by the license sticker on the host machine.
Most Dell's include a VHD that uses the same OEM activation as the host. Check in C:\Dell_OEM on the host machine. If there is a VHDX file in there, you can simply mount that in your VM to get a Dell OOBE version of Server 2016, VM-ready.
