Re: Cannot specify host in availability zone

Hi Mauricio, Faced similar issue. Maybe my issue and idea will help you. First try same steps from horizon. Second. In cli, i used same name as hypervizor list output. In most cases for me it is: $stackName-$roleName-$index.localdomain if forget to change localdomain value ;)) My faced issues were related, tah one compute can be in one zone, and multiple aggregation groups in same zone. Note: Interesting that you use nova blah-blah, try openstack aggregate create zonename --zone zonename And same with openstack aggregate help see help how to add it with openstack. Hope this helps at least a bit.
