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.
