| # Partial paths look like relative filenames. They do not begin |
| # with a prefix. The matching rules for partial paths are subtle but |
| # designed to make specifying objects easy. At each level of the |
| # composition tree, the partial path is matched as an absolute path. |
| # The first match is not returned. At least two matches are searched |

| # @dump-guest-memory |
| # |
| # 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 on i386 and x86_64. |
| # |
| # @paging: if true, do paging to get guest's memory mapping. This allows |

| # 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. |
