But we already have to call 'qemu -h' for other reasons; so we might as well be efficient and learn as much as possible from that result than by calling both 'qemu -h' and 'qemu -qmp ...', in order to probe what qemu supports.
Also, 'qemu -qmp' doesn't work. What's the proper syntax for invoking qemu in order to query QMP capabilities, but without also starting up a guest?
anthony@titi:~/build/qemu$ (sleep 1; echo -e '{"execute": "qmp_capabilities"}\n{"execute": "quit"}') | x86_64-softmmu/qemu-system-x86_64 -qmp stdio -S -display none | head -1 {"QMP": {"version": {"qemu": {"micro": 94, "minor": 15, "major": 0}, "package": ""}, "capabilities": []}}
Doesn't work on 0.12 (the first version with qmp):
There's another problem lurking here, and I think it's a more serious one: I don't we are doing proper integration tests with libvirt (we == qemu, but mostly me). My tests are sporadic and mostly manual (I used to use libvirt-tck, but it's been a while since I ran it last time). Is libvirt-tck the recommended way to run integration tests? If it's we should be running it frequently.
