Description of problem: Any reasonable deployment needs more than one conductor process and grizzly did not support this natively. Right now, this is only workable if someone runs a conductor on several machines or starts multiple processes manually. We should have an /etc/sysconfig/nova-conductor config point to specify how many daemons to start so that it's easy to start multiple daemons on a single system. Version-Release number of selected component (if applicable): openstack-nova-conductor-2013.1.3-3.el6ost How reproducible: Very. Steps to Reproduce: 1. Deploy conductor on one machine 2. Deploy compute on many machines 3. Notice failures and poor performance Actual results: Everything funnels through a single conductor. Expected results: Multiple conductors should be started to spread out the load. Additional info: This should be pretty easy to do in the script, starting multiple workers, with log files and pid files like /var/log/nova/conductor-$i.log, etc.
VERIFICATION: 1. Deploy conductor node and at least one compute node 2. Alter workers param of the [conductor] section of /etc/nova/nova.conf to workers=2 3. Restart the openstack-nova-conductor service 4.
