Hi, I have a multi-node setup with 2 compute hosts, qa5 and qa6.
I created 2 host-aggregate, each with its own availability zone, and assigned
one compute host:
localadmin@qa4:~/devstack$ nova aggregate-details host-aggregate-zone-1
+----+-----------------------+-------------------+-------+--------------------------+
| Id | Name | Availability Zone | Hosts | Metadata
|
+----+-----------------------+-------------------+-------+--------------------------+
| 9 | host-aggregate-zone-1 | az-1 | 'qa5' |
'availability_zone=az-1' |
+----+-----------------------+-------------------+-------+--------------------------+
localadmin@qa4:~/devstack$ nova aggregate-details host-aggregate-zone-2
+----+-----------------------+-------------------+-------+--------------------------+
| Id | Name | Availability Zone | Hosts | Metadata
|
+----+-----------------------+-------------------+-------+--------------------------+
| 10 | host-aggregate-zone-2 | az-2 | 'qa6' |
'availability_zone=az-2' |
+----+-----------------------+-------------------+-------+—————————————+
My intent is to control at which compute host to launch a VM via the
host-aggregate’s availability-zone parameter.
To test, for vm-1, I specify --availiability-zone=az-1, and
--availiability-zone=az-2 for vm-2:
localadmin@qa4:~/devstack$ nova boot --image cirros-0.3.2-x86_64-uec --flavor 1
--nic net-id=5da9d715-19fd-47c7-9710-e395b5b90442 --availability-zone az-1 vm-1

However, both VMs ended up at compute host qa5:

Is it supposed to work this way? Do I missed something here?
Thanks,
