Annotated Snippet

--guestmount=<path>::
	Guest OS root file system mount directory. Users mount guest OS
	root directories under <path> by a specific filesystem access method,
	typically, sshfs.
	For example, start 2 guest OS, one's pid is 8888 and the other's is 9999:
[verse]
	$ mkdir \~/guestmount
	$ cd \~/guestmount
	$ sshfs -o allow_other,direct_io -p 5551 localhost:/ 8888/
	$ sshfs -o allow_other,direct_io -p 5552 localhost:/ 9999/
	$ perf {GMEXAMPLECMD} --guestmount=~/guestmount {GMEXAMPLESUBCMD}

Annotation

• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
