I'd like a clarification of terms. What is a host partition? What is a guest partition. If someone says "Currently it's one hosted and two guested LPARS", what does that mean? What is the difference between "hosted" and "guested"?
Some references suggest that a "guest" runs under the primary operating system, such as Linux running under a Windows VM. Windows is the "host", while Linux is the "guest". If Windows fails to boot, then there would be no way to reach Linux, for example.
