Comment 4 for bug 1495925

So this sounds like a feature request to me:

currently nova-compute (technically, any other nova-* service) reports its state only based on its own availability and knows nothing about implementation specific details, like vcenter API in case of vmware compute driver.

I suggest we do this upstream first, hence marking as Wishlist. Unfortunately, it's too late to propose this for Mitaka, but we can give it a try in N releae.
