At the moment I am reviewing the Installation Guide for openSUSE. For the Nova controller I should install the openstack-nova-cert package. Is this really necessary? nova-cert is only required by the EC2 API (http://docs.openstack.org/developer/nova/man/nova-cert.html) and I think it should not be installed by default.
