I don't see why, either.
I'm CCing libvir-list and the people involved in the code that
added halt state to libvirt domain statistics.
I've posted a libvirt patch to disable query-cpus in the domain stats
collection for all architectures other than s390. This should alleviate
the problem until we have a better method to obtain arch-specific cpu state.
