[Openstack-operators] Instance Scheduling on Hosts

I ended up successfully in creating flavors with aggregate hosts 
metadata and the filter you mentioned on my Folsom install.

I followed the same configuration steps [1]

What kind of error are you getting ? Is nova-scheduler failing or 
nova-compute ? Check the logs to get the exact error, please :-)
