Yesterday my friend Kalen Delaney asked me about @@VERSION showing (HYPERVISOR) even though she wasn’t running inside a virtual machine. I was able to replicate the behavior on my machines. I asked my colleagues at Microsoft about this. It was confirmed that it is by design. The addition of (HYPERVISOR) to the output indicates only whether or not Hyper-V is currently enabled on the machine. It is not intended to indicate if SQL Server is running inside a Hyper-V virtual machine. Disable Hyper-V on the machine and the text goes away.
I did not have access to any machines with hypervisors other than Hyper-V.
If you didn’t intentionally enable Hyper-V on your machine, installing Visual Studio can do that depending on the options you selected.
