Hi Folks,

I'm setting up quantum with linux bridge. I might have configured this
incorrectly and looking for some help on what could be going on.

This is my quantum.conf  and linuxbridge_conf.ini - which tries to setup
the linux bridge over eth2.

[DEFAULT]
auth_strategy = keystone
allow_overlapping_ips = True
policy_file = /etc/quantum/policy.json
debug = True
verbose = True
service_plugins =
quantum.plugins.services.agent_loadbalancer.plugin.LoadBalancerPlugin
core_plugin =
quantum.plugins.linuxbridge.lb_quantum_plugin.LinuxBridgePluginV2
rabbit_password = openstack
rabbit_host = localhost
rpc_backend = quantum.openstack.common.rpc.impl_kombu
state_path = /opt/stack/data/quantum
debug = True
verbose = True
lock_path = $state_path/lock
log_file = quantum.log
log_dir = /var/log/quantum
bind_host = 0.0.0.0
bind_port = 9696
<......>

linuxbridge_conf.ini

[VLANS]
tenant_network_type = vlan
network_vlan_ranges = physnet2:1000:2999
[DATABASE]
sql_connection = mysql://root:openstack@localhost
/quantum_linux_bridge?charset=utf8
reconnect_interval = 2
[LINUX_BRIDGE]
physical_interface_mappings = physnet2:eth2
[AGENT]
root_helper = sudo /usr/local/bin/quantum-rootwrap
/etc/quantum/rootwrap.conf
polling_interval = 2
[SECURITYGROUP]
firewall_driver =
quantum.agent.linux.iptables_firewall.IptablesFirewallDriver

But when the VM is booted up, it comes up over brq3c2d19b3-fa instead of
br-eth2

bridge name     bridge id               STP enabled     interfaces
br-eth2         8000.000cfc01f473       no              eth2
brq057a0be8-e9          8000.96f0115f0c03       no
 tapa0dcbf6a-73
brq34f87736-91          8000.32245b5d90b7       no
 tap22c7ffb1-9f

                             tap874fecfb-ac
brq3c2d19b3-fa          8000.3a84ed127b7a       no
 tapadbf1b11-e9

                            tapc6c54b78-87

                            tapcf424b48-54

                           tapdb58671d-bd

                            tapdb661e2b-ff

Here's a list of commands :

quantum net-create sharednet1 --shared --provider:network_type=flat -
provider:physical_network=physnet2
quantum subnet-create sharednet1 30.0.0.0/24

+--------------------------------------+------------+------------------------------------------------------+

nova boot --image cirros --flavor m1.tiny --nic
net-id=3c2d19b3-fa72-4bcb-916b-8d54e0e879b1 --key-name test my_first_server

Anything I'm missing ?

Thanks !
