Hi Joe,

No, I did not.  I’m not aware of this.

Can you tell me exactly what needs to be done?

Thanks,
Danny

Did you enable the AvailabilityZoneFilter in nova.conf that the scheduler uses?  And enable the FilterScheduler?  These are two common issues related to this.

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:

| 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:
