i think what is actully wanted is "openstack server create --nic net-id=<your network>,v4-fixed-ip=<ip-addr>" we do not have a subnet-id option for --nic so if you want to select the subnet as part of the boot you have to supply the ip. similary if you want neutron to select the ip you have to precreate teh port and use the --port option when creating the vm. so as matt saidn #3 or #4 are the best solutions for your request. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
