When probing QEMU capabilities fails for a binary generate a log message with MESSAGE_ID==8ae2f3fb-2dbe-498e-8fbd-012d40afa361. This can be directly queried from journald based on the UUID instead of needing string grep. This lets tools like libguestfs' bug reporting tool trivially do automated sanity tests on the host they're running on. $ journalctl MESSAGE_ID=8ae2f3fb-2dbe-498e-8fbd-012d40afa361 Feb 21 17:11:01 localhost.localdomain lt-libvirtd[9196]: Failed to probe capabilities for /bin/qemu-system-alpha: internal error: Child process (LC_ALL=C LD_LIBRARY_PATH= /home/berrange/src/virt/libvirt/src/.libs PATH=/usr/lib64/ ccache:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin: /usr/bin:/root/bin HOME=/root USER=root LOGNAME=root /bin/qemu-system-alpha -help) unexpected exit status 127: /bin/qemu-system-alpha: error while loading shared libraries: libglapi.so.0: cannot open shared object file: No such file or directory $ journalctl MESSAGE_ID=8ae2f3fb-2dbe-498e-8fbd-012d40afa361 --output=json { ...snip...
