The goal would be to have something like what he attached to his email (the strace output) for our failing case on merlot. That's assuming that what Anthony have done to get the traces could be put in a patch to libxl and/or libvirt, apply it to some branch, and make the ad-hoc test pick code for the proper components from such branch... which, I think, should all be doable, or am I talking nonsense?
