We did not as yet do any work to extend reporting of information about compute hosts to the cloud admin. There is obviously some scope todo that so they can do capacity reporting & planning more effectively. Note however that we explicitly don't want to go in the direction of having the users explicitly requesting resources from specific hosts based on this kind of info.
