Devstack isn't for production. I recommend using packages (even if they are your own).
repeat: WHAT FOLLOWS IS NOT FOR PRODUCTION! If you are just experimenting with a multi-node dev deploy - you can set a few options in your nova.conf: --sql_connection=mysql://$MYSQL_USER:$PASS@$MASTER_IP/nova --rabbit_host=$MASTER_IP --rabbit_password=$RABBIT_PASS --glance_api_servers=$MASTER_IP:9292 My team (creators of devstack) do a multi-node devstack deploys every day (for development - for production we use crowbar/chef, ubuntu, and package) With devstack on multiple nodes you can create a localrc how you normally would then add: master node: you need all the services ENABLED_SERVICES=n-vol,g-api,g-reg,key,n-api,n-cpu,n-net,n-sch,n-vnc,horizon,mysql,rabbit,swift,openstackx child nodes: you only need the workers MYSQL_HOST=$MASTER_IP RABBIT_HOST=$MASTER_IP GLANCE_HOSTPORT=$MASTER_IP:9292 ENABLED_SERVICES=n-vol,n-cpu,n-net,n-api notes: * we run n-api on each node to provide the metadata service (you can also setup iptables routes to forward requests to the metadata service to the main nova-api node). We plan on switching to https://github.com/openstack/nova/blob/master/bin/nova-api-metadata on the child nodes. * we use --network_manager=nova.network.manager.FlatDHCPManager with --force_dhcp_release --multi_host and --send_arp_for_ha On Tue, Dec 27, 2011 at 10:05 AM, Kiall Mac Innes <ki...@managedit.ie> wrote: > It sounds like you are trying to use devstack for a production install, this > is not recommended.
