Yes, I'm aware of that; that isn't relevant to my question.
I would expect the *total* memory requested by a VM to never go over
the hard_limit value set in the XML file. I mean, isn't that what
the hard_limit *means*? If not, what does it mean?
That's certainly what
http://libvirt.org/formatdomain.html#elementsMemoryTuning *implies*,
anyways.
