1788 # @dump-guest-memory
1789 #
1790 # Dump guest's memory to vmcore. It is a synchronous operation that can take
1791 # very long depending on the amount of guest memory. This command is only
1792 # supported only on i386 and x86_64
1793 #
1794 # @paging: if true, do paging to get guest's memory mapping. The @paging's
1795 # default value of @paging is false, If you want to use gdb to process the
1796 # core, please set @paging to true. The reason why the @paging's value is
1797 # false:
1798 # 1. guest machine in a catastrophic state can have corrupted memory,
1799 # which we cannot trust.
1800 # 2. The guest machine can be in read-mode even if paging is enabled.
1801 # For example: the guest machine uses ACPI to sleep, and ACPI sleep
1802 # state goes in real-mode
1803 # @protocol: the filename or file descriptor of the vmcore. The supported
1804 # protocol can be file or fd:
1805 # 1. file: the protocol starts with "file:", and the following string is
1806 # the file's path.
1807 # 2. fd: the protocol starts with "fd:", and the following string is the
1808 # fd's name.
1809 # @begin: #optional if specified, the starting physical address.
1810 # @length: #optional if specified, the memory size, in bytes. If you don't
1811 # want to dump all guest's memory, please specify the start @begin and
1812 # @length
1813 #
1814 # Returns: nothing on success
1815 # If @begin contains an invalid address, InvalidParameter
1816 # If only one of @begin and @length is specified, MissingParameter
1817 # If @protocol stats with "fd:", and the fd cannot be found, FdNotFound
1818 # If @protocol starts with "file:", and the file cannot be
1819 # opened, OpenFileFailed
1820 # If @protocol does not start with "fd:" or "file:", InvalidParameter
1821 # If an I/O error occurs while writing the file, IOError
1822 # If the target does not support this command, Unsupported
