Hmm, I'm not sure I like this. It turns a relatively minor 'gotcha' of
the hypervisor interface into something that's more confusing: if you're
trying to iterate over domains using xc_domain_getinfo then you have to
ask for at least two domains at a time otherwise you'll get ESRCH.

I think the cleanest fix is just to add an 'iterate' flag to the
parameters in GETDOMAININFO, no?
