flat network cannot be created with Quantum LinuxBridge plugin
Last modified: 2014-02-27 18:17:24 EST
When creating the "--provider:network_type flat" network with the Quantum LinuxBridge plugin, for example, # quantum net-create public01 --tenant-id xxxx --provider:network_type flat --provider:physical_network physnet1 it fails with the following error. "Invalid input for operation: unknown provider:physical_network physnet1" even if the corresponding entry is in /etc/quantum/plugin.init, like: --- [LINUX_BRIDGE] physical_interface_mappings = physnet1:eth1 --- And the culprit is here... /usr/lib/python2.6/site-packages/quantum/plugins/linuxbridge/lb_quantum_plugin.py 291 if network_type in [constants.TYPE_VLAN, constants.TYPE_FLAT]: 292 if physical_network_set: 293 if physical_network not in self.network_vlan_ranges: 294 msg = _("unknown provider:physical_network %s" % 295 physical_network) 296 raise q_exc.InvalidInput(error_message=msg) 297 elif 'default' in self.network_vlan_ranges: 298 physical_network = 'default' 299 else: 300 msg = _("provider:physical_network required") 301 raise q_exc.InvalidInput(error_message=msg) 302 303 return (network_type, physical_network, segmentation_id) In this part, physical_network is searched in self.network_vlan_ranges both for TYPE_VLAN and TYPE_FLAT. TYPE_FLAT should be checked differently. My setup is: # rpm -qf /usr/lib/python2.6/site-packages/quantum/plugins/linuxbridge/lb_quantum_plugin.py openstack-quantum-linuxbridge-2012.2-2.el6.noarch
The physical_interface_mappings configuration variable is used only by the agent, not the server. You need to list the physical network in the server's network_vlan_ranges configuration variable to tell the server about it, even if you are not using any VLANs on it. Don't forget that the same physical network might support a flat network in addition to provider VLANs and/or tenant VLANs. Try adding something like the following to linuxbridge_conf.ini on the server: [VLANS] network_vlan_ranges = physnet1 -Bob
I see. Your suggstion for linuxbridge_conf.ini worked well. So, this is rather a documentation problem. (The Quantum part of the current Folsom Preview documentation is confusing --- not well merged with the other parts, by the way.) Anyway, I agree to close this BZ. Thanks.
