nova aggregate-list shows all aggregates.

nova aggregate-details name-of-aggregate shows the hosts in that aggregate. I don't know if it's possible to do the opposite - look up a host to find its aggregate(s).

What do you mean by HA zone - perhaps availability zone? nova availability-zone-list shows all the availability zones and the hosts that belong to them. Note that an availability zone is essentially the same as a host aggregate, see here.

By the way, you don't need libvirt to find the host that an instance runs on. nova show instance-name gives you that information if you are an admin user.
