Hello, everyone: I am installing the OpenStack Pike on some node. Although the previours step are all successful the last step, launch a instance, is prevented by a problem as following: There is no qroute namespace after I create a virtual router that link a provider network and a private network and the two port of the router are all in down status!

[root@controller neutron]# ip netns

qdhcp-21122cd3-f2e9-485d-b72b-6db8f80a6ad2 (id: 1) qdhcp-12c176e7-5c6c-47f3-9f41-5cfdf4785a14 (id: 0) [root@controller neutron]#

[root@controller ~]# openstack port list --router router

The key fragment of the error log, l3-agent.log, is as this: 2018-09-29 08:32:23.092 1076 ERROR neutron.agent.l3.router_info IpTablesApplyException: Failure applying iptables rules 2018-09-29 08:32:23.094 1076 ERROR neutron.agent.linux.iptables_manager [-] Failure applying iptables rules: OSError: [Errno 13] Permission denied: '/var/ib' 2018-09-29 08:32:23.094 1076 ERROR neutron.agent.linux.iptables_manager OSError: [Errno 13] Permission denied: '/var/ib'
