Sorry for the newbie question, but I could not find an answer for it.
I have a Windows 2008 R2 Server in production running some applications, and I need to create a Virtual Machine to run a very light workload in that server to isolate another application, and keep running the actual applications on the "host".
I've read somewhere that when one adds the Hyper-V role on Windows 2008 R2 Server, the actual Windows installation becomes somewhat a "guest", running inside Hyper-V (because Hyper-V is a hypervisor).
It is safe to add the Hyper-V role in Windows already running on production? Should I expect breakages on the actual "host"?
