Comment 0 for bug 1504255

The os-server-groups API in nova takes an all_projects parameter that is not documented in api-site:

http://developer.openstack.org/api-ref-compute-v2.1.html#listServerGroups

This is related to nova bug 1503042.

Basically as long as the query parameter exists in the request (value doesn't matter) and it's an admin tenant, it will list all server groups in all tenants.
