The hyper-v driver uses WMI.
Libvirt is not used.   There is currently no support for celometer, however we should have havana blueprints meaning it is one of the things we are trying to deliver.

First question is, is Hyper-V driver for Nova used via libvirt?
If yes, then libvirt should be "patched" to provide information to
Ceilometer.
If not, then Ceilometer should be patched to learn how to poll Hyper-V.
