OpenStack Notes

To force usage of keystone’s v3 API:

  • Download openrc
  • Adjust OS_AUTH_URL to use “v3” instead of “v2.0”. From export OS_AUTH_URL=http://192.168.100.100:5000/v2.0 to export OS_AUTH_URL=http://192.168.100.100:5000/v3
  • Pass the --os-identity-api-version=3 flag to the openstack command:
    • openstack --os-identity-api-version=3 server list
    • Other commands (like nova) may not be updated to use the v3 keystone authentication API.

To receive DHCP packets in a VM under KVM (for instance, as one would want to do for a FUEL server):

  • One must disable iptables from running on the bridge interface.
