RHEL6.4安裝openstack g版遇到的問題，哪位大俠知道這是什么問題嗎？

復制代碼

從上面日志看，是openstack執(zhí)行命令ip netns add qdhcp-85cb370c-209e-483c-9581-8f14afb94aa8失敗。為此，我直接在shell中敲命令，結(jié)果一樣：

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

復制代碼

我查看了/proc/self目錄，并沒有ns子目錄。

哪位大俠知道原因嗎？謝謝。

1. 執(zhí)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，好像要編譯內(nèi)核，加上參數(shù)CONFIG_NET_NS=y

恩，多謝。最后證明該源里的kernel雖然能解決改問題，但是配置多節(jié)點openvswitch vlan存在問題，最后還是使用kernel 3.5.0才最終部署成功。gre即使在3.5.0內(nèi)核上也有問題。

6.4對于那些功能都不算預覽，6.5開始一些功能是預覽，然后再下一個版本是正式

按照你上述方法能解決掉 l3-agent.log日志中的錯誤。

對于網(wǎng)絡這塊還往多指教！

    標準內(nèi)核,現(xiàn)在3.11.0應該支持openvswitch了，不過我還沒有試

回復 9# Hongqiyaodao


   系統(tǒng)初始安裝的RHEL6.4，通過內(nèi)核源碼安裝升級的，源碼來自www.kernel.org，沒有使用Grizzly源中提供的那個內(nèi)核。那個內(nèi)核使用openvswitch vlan好像有問題，反正我用它沒有成功。
