Code looks good, but it fails make syntax-check here in my env:
cppi: src/qemu/qemu_agent.c: line 2360: not properly indented
cppi: tests/qemuagenttest.c: line 1127: not properly indented
maint.mk: incorrect preprocessor indentation
make: *** [cfg.mk:699: sc_preprocessor_indentation] Error 1
make: *** Waiting for unfinished jobs.
Thanks,
DHB
