(Originally this was designed to show statistics by '{"execute": "query-cryptodev"}'. Daniel Berrangé suggested that querying configuration info by "query-cryptodev", and querying runtime performance info by "query-stats". This makes sense!) Example: ~# virsh qemu-monitor-command vm '{"execute": "query-stats", \ "arguments": {"target": "cryptodev"} }' | jq { "return": [ { "provider": "cryptodev", "stats": [ { "name": "asym-verify-bytes", "value": 7680 }, ... { "name": "asym-decrypt-ops", "value": 32 }, { "name": "asym-encrypt-ops", "value": 48 } ], "qom-path": "/objects/cryptodev0" # support asym only }, { "provider": "cryptodev", "stats": [ { "name": "asym-verify-bytes", "value": 0 }, ... { "name": "sym-decrypt-bytes", "value": 5376 }, ... ], "qom-path": "/objects/cryptodev1" # support asym/sym } ], "id": "libvirt-422" } Suggested-by: Daniel P.
