Guest memory dump function

 Overview of guest memory dump function
(1) Overview
The guest memory dump function saves memory data as a file by executing the
HVM Management Command (HvmSh) on the LPAR manager management server.
The function collects memory data (memory dump) allocated to the specified guest
(LPAR) on the LPAR manager side by executing HvmSh. Then it transfers the
collected data to the external File Transfer Protocol (FTP) server to save it as a file.
This function allows memory dump even if a logical server error occurs, such as
when OS dump data cannot be collected by the guest OS, and can be used for
analyzing logical server errors.
