This is the forth (and maybe final) pass at enabling getting debug information from QEMU via the Qemu Machine Protocol interface. The Qemu source provides a qmp.py module which is installed in the recipe-sysroot-native site-packages.
The initial commands that are issued to qmp when a failure is detected are: query-status and query-block. The output goes into formated json files as follows: tmp/log/runtime-hostdump/202101061054_qmp ├── qmp_00_query-block ├── qmp_00_query-status ├── qmp_01_query-block └── qmp_01_query-status This has been tested by calling the monitor_dump code directly in the target/ssh.py code instead of waiting for a given failure. This version adds a time-out loop to check for the Unix Socket file that was being problematic on the CentOS-8 builders. Sau!
