    The command's usage:
       dump-guest-memory [-p] protocol [begin] [length]
    The supported protocol can be file or fd:
    1. file: the protocol starts with "file:", and the following string is
       the file's path.
    2. fd: the protocol starts with "fd:", and the following string is the
       fd's name.
    
    Note:
      1. If you want to use gdb to process the core, please specify -p option.
         The reason why the -p option is not default is:
           a. guest machine in a catastrophic state can have corrupted memory,
              which we cannot trust.
           b. The guest machine can be in read-mode even if paging is enabled.
              For example: the guest machine uses ACPI to sleep, and ACPI sleep
              state goes in real-mode.
      2. If you don't want to dump all guest's memory, please specify the start
         physical address and the length.
