我的实例在Openstack中工作:连接到nova.clouds.ubuntu无法启动连接 [英] Openstack working from my instance: Connecting to nova.clouds.ubuntu Cannot initiate connection

问题描述

我是Openstack的新手，我已经使用devstack安装了它.我使用具有热度的ubuntu服务器云映像启动了一个实例.我可以ssh到实例.问题是在尝试执行操作时:

I am new to Openstack, I've installed it using devstack. I launched an instance using ubuntu server cloud image with heat flavor. I can ssh to the instance. The problem is when trying to do:

sudo apt-get update

sudo apt-get install openjdk-7-jdk

我有

0％(连接到nova.clouds.archive.ubuntu.com ip @)

0% (connecting to nova.clouds.archive.ubuntu.com ip@)

它不断更改ip @，然后错误无法启动与nova connect的连接(101:网络无法访问)

It keeps changing the ip@ then error cannot initiate connection to nova connect(101: network unreachable)

我正在将浮动IP关联到我的实例

I am associating floating IP to my instance

推荐答案

我必须在主机中执行sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
