# Dump guest's memory to vmcore. It is a synchronous operation that can take
# very long depending on the amount of guest memory. This command is only
-# supported only on i386 and x86_64

-# @paging: if true, do paging to get guest's memory mapping. The @paging's
-# default value of @paging is false, If you want to use gdb to process the
-# core, please set @paging to true. The reason why the @paging's value is
-# false:
-# 1. guest machine in a catastrophic state can have corrupted memory,
-# which we cannot trust.
-# 2. 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

+# @paging: if true, do paging to get guest's memory mapping. This allows

+# may be desirable because of two reasons:

+# memory, which cannot be trusted
+# 2. The guest can be in real-mode even if paging is enabled. For example,
