neutron创建虚拟路由器，端口状态为down

[lawn212]

操作步骤如下：
1、创建两个子网
neutron net-create private
neutron net-create private1
neutron subnet-create private 192.168.10.0/24 --name private --dns-nameserver 219.141.136.10 --gateway 192.168.10.1
neutron subnet-create private1 192.168.11.0/24 --name private1 --dns-nameserver 219.141.136.10 --gateway 192.168.11.1
2、创建虚拟路由器，并将创建的子网关联上去
neutron router-create router
neutron router-interface-add router private
neutron router-interface-add router private1
3、查看路由器端口
neutron router-port-list router
结果如下：
| id | name | mac_address | fixed_ips |
+--------------------------------------+------+-------------------+-------------------------------------------------------------------------------------+
| 06f2f8c7-3961-4b29-a1a2-847cce3730ed | | fa:16:3e:c2:5f:14 | {"subnet_id": "cf65aa8c-23ef-4f2f-b808-7f5abd43525e", "ip_address": "192.168.11.1"} |

4、查看端口状态
neutron port-show 921916c2-c611-45ed-af10-49af992a8192

第一个端口状态是ACTIVE，第二个端口状态是DOWN，请问如何查找端口DOWN的原因呢？

问题解决： 修改模块文件/lib/python2.7/site-packages/neutron/agent/linux/ip_lib.py相应内容如下： ...... @classmethod def get_namespaces(cls): output = cls._execute([], 'netns', ('list',)) return [l.split()[0] for l in output.splitlines()] ...... def exists(self, name): output = self._parent._execute( ['o'], 'netns', ['list'], run_as_root=cfg.CONF.AGENT.use_helper_for_ns_read) for line in [l.split()[0] for l in output.splitlines()]: if name == line: return True return False ...... 目前官网已经修复此BUG，你也可以直接通过yum upgrade升级系统包解决。 原文链接：https://review.openstack.org/#/c/258493

我的版本的修改过的了，但是，创建的接口还是down啊
