Hi,
I want to make a kind of relational model :
Instance <-> host <-> host aggregate <-> HA zone
I know how to retrieve , from a piece of code running on host, instance and host UUIDs ( using libvirt). How may I retrieve host aggregate and HA zone UUIDs to which instance and host belongs ?
Thx for help.

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.
