I have a need to deploy a given VM on a specific host in my OpenStack Icehouse cluster, bypassing availability zones entirely.
To help with this, I've attempted the following: 1. Created Host Aggregate. Each contains a single host and metadata of the form 'host=hostname' (e.g., 'host=myhost'). 2. Edited nova.conf to include the following (and restarted nova-schedule): scheduler_default_filters = AggregateInstanceExtraSpecsFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter Reference: http://docs.openstack.org/icehouse/config-reference/content/section_compute-scheduler.html#d6e8083 3. In my Heat template's OS::Nova::Server properties, I've added: scheduler_hints: {host: myhost} 4. In my Heat template's outputs, I've added: host: description: The host myserver resides on. value: {get_attr: [myserver, show, 'OS-EXT-SRV-ATTR:host']} When I try this, it doesn't seem to have any effect on the host selected. I suspect pilot error, perhaps in the scheduler_hints step? Clues welcome/appreciated! jd _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
