15# Arguments:
16#
17# @enable:   An optional list of QMPCapability values to enable.  The
18#            client must not enable any capability that is not
19#            mentioned in the QMP greeting message.  If the field is not
20#            provided, it means no QMP capabilities will be enabled.
21#            (since 2.12)

27# <- { "return": {} }

29# Notes: This command is valid exactly when first connecting: it must be
30# issued before any other command will be accepted, and will fail once the
31# monitor is accepting other commands. (see qemu docs/interop/qmp-spec.txt)
32#
33# The QMP client needs to explicitly enable QMP capabilities, otherwise
34# all the QMP capabilities will be turned off by default.

1691# Dump guest's memory to vmcore. It is a synchronous operation that can take
1692# very long depending on the amount of guest memory.
1693#
1694# @paging: if true, do paging to get guest's memory mapping. This allows
1695#          using gdb to process the core file.
1696#
1697#          IMPORTANT: this option can make QEMU allocate several gigabytes
1698#                     of RAM. This can happen for a large guest, or a
1699#                     malicious guest pretending to be large.
1700#
1701#          Also, paging=true has the following limitations:
1702#
1703#             1. The guest may be in a catastrophic state or can have corrupted
1704#                memory, which cannot be trusted
1705#             2. The guest can be in real-mode even if paging is enabled. For
1706#                example, the guest uses ACPI to sleep, and ACPI sleep state
1707#                goes in real-mode
1708#             3. Currently only supported on i386 and x86_64.

1715#            2. fd: the protocol starts with "fd:", and the following string
1716#               is the fd's name.
1717#
1718# @detach: if true, QMP will return immediately rather than
1719#          waiting for the dump to finish. The user can track progress
1720#          using "query-dump". (since 2.6).
