OpenStack agent: Reconfiguring agent instances to use OpenStack identity API v3

To upgrade the OpenStack agent to use OpenStack identity API v3, after you install the latest version of the agent, you must reconfigure all agent instances and update the data collector configuration file.

1. Reconfigure all existing agent instances. For detailed instructions, see Configuring the OpenStack agent.
2. Find the ksg_dc_instance_name.cfg agent data collector configuration file, where instance_name is the name you specified for your agent instance.
   If the file does not exist, copy install_dir/lx8266/sg/bin/ksg_dc.cfg to the install_dir/config directory and change the file name to ksg_dc_instance_name.cfg.
   For example, if the instance name is OS1, change the name to ksg_dc_OS1.cfg.
3. Add the following section to the ksg_dc_instance_name.cfg file:

   #OpenStack authentication information
   [OS_authentication_info]
   OS_project_domain_name=Default
   OS_user_domain_name=Default
   OS_cert_path=

4. Restart the agent instance by running the following commands:

   install_dir/bin/openstack-agent.sh stop instance_name
   install_dir/bin/openstack-agent.sh start instance_name

   where instance_name is the name of the agent instance to be configured.
