基于davstack搭建openstack folsom开发环境（2）
二.安装quantum模块
??? 首先，需要保证quantum的版本和其他模块的版本匹配（我安装的是quantum-2012.2版本），否则会出如下错误：
sed -i 's/sql_connection = sqlite:\/\//sql_connection = mysql:\/\/root:123456@localhost\/ovs_quantum/g' /etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini sed -i '24a tenant_network_type = none' /etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini sed -i '36a network_vlan_ranges = physnet1' /etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini sed -i '43a enable_tunneling = False' /etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini sed -i '60a integration_bridge = br-int' /etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini sed -i '81a bridge_mappings = physnet1:br-int' /etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini
