RHEL6.4安装openstack g版遇到的问题，哪位大侠知道这是什么问题吗？

复制代码

从上面日志看，是openstack执行命令ip netns add qdhcp-85cb370c-209e-483c-9581-8f14afb94aa8失败。为此，我直接在shell中敲命令，结果一样：

1. [root@server8 quantum]# ip netns add qdhcp-85cb370c-209e-483c-9581-8f14afb94aa8
   
2. Bind /proc/self/ns/net -> /var/run/netns/qdhcp-85cb370c-209e-483c-9581-8f14afb94aa8 failed: No such file or directory

复制代码

我查看了/proc/self目录，并没有ns子目录。

哪位大侠知道原因吗？谢谢。

1. 执行wget http://repos.fedorapeople.org/re ... nstack-grizzly.repo -O /etc/yum.repos.d/epel-openstack-grizzly.repo

2. yum --disablerepo=* --enablerepo=epel-openstack-grizzly update -y kernel iputils iproute

然后就可以了

    看了下配置文件，好像要编译内核，加上参数CONFIG_NET_NS=y

恩，多谢。最后证明该源里的kernel虽然能解决改问题，但是配置多节点openvswitch vlan存在问题，最后还是使用kernel 3.5.0才最终部署成功。gre即使在3.5.0内核上也有问题。

6.4对于那些功能都不算预览，6.5开始一些功能是预览，然后再下一个版本是正式

按照你上述方法能解决掉 l3-agent.log日志中的错误。

对于网络这块还往多指教！

    标准内核,现在3.11.0应该支持openvswitch了，不过我还没有试

   系统初始安装的RHEL6.4，通过内核源码安装升级的，源码来自www.kernel.org，没有使用Grizzly源中提供的那个内核。那个内核使用openvswitch vlan好像有问题，反正我用它没有成功。
