Options:

--domain-id DOMAIN_ID

-h, --help print help

The following options require you to specify an id:

--architecture-id ARCHITECTURE_ID  
    --domain-id DOMAIN_ID          
    --environment-id ENVIRONMENT_ID  
    --medium-id MEDIUM_ID          
    --operatingsystem-id OPERATINGSYSTEM_ID  
    --parent-id PARENT_ID          
    --ptable-id PTABLE_ID          
    --puppet-ca-proxy-id PUPPET_CA_PROXY_ID  
    --puppet-proxy-id PUPPET_PROXY_ID  
    --puppetclass-ids PUPPETCLASS_IDS Comma separated list of values.
    --realm-id REALM_ID            
    --subnet-id SUBNET_ID

There should be someway to do all this without referencing the ID.
