|

# Dump guest's memory to vmcore. It is a synchronous operation that can take

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

# using gdb to process the core file.

# IMPORTANT: this option can make QEMU allocate several gigabytes
|
|
# of RAM. This can happen for a large guest, or a
|
|
# malicious guest pretending to be large.
|
|
#
|
|
# Also, paging=true has the following limitations:
|
|
#
|
|
# 1. The guest may be in a catastrophic state or can have corrupted
|
|
# memory, which cannot be trusted
|
|
# 2. The guest can be in real-mode even if paging is enabled. For

|
# example, the guest uses ACPI to sleep, and ACPI sleep state
|
|
# goes in real-mode

|
#
|
|
# @protocol: the filename or file descriptor of the vmcore. The supported
|
|
# protocols are:
|
|
#
|
|
# 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.
