问题导读

1.如何查看iptables规则？
2.如何查看filter表规则？
3.本文是如何分析问题解决问题的？




1、问题现象

版本：Grizzly master分支代码2013.06.17
部署：三个节点（Controller/Compute + Network + Compute）
使用的镜像：precise-server-cloudimg-i386-disk1.img
创建虚拟机命令：nova boot ubuntu-keypair-test --image 1f7f5763-33a1-4282-92b3-53366bf7c695 --flavor 2 --nic net-id=3d42a0d4-a980-4613-ae76-a2cddecff054 --availability-zone nova:compute233 --key_name mykey

虚拟机ACTIVE之后，可以ping通虚拟机的fixedip（10.1.1.6）和floatingip（192.150.73.5）。VNC访问虚拟机正常，出现登录界面。因为Ubuntu的镜像无法使用密码登录，所以只能通过SSH访问，这也是创建虚拟机时指定key_name的原因。

在NetworkNode通过ssh登录虚拟机失败：
  1. root@network232:~# ssh -i mykey.pem ubuntu@192.150.73.5 -v 

  2. OpenSSH_5.9p1 Debian-5ubuntu1.1, OpenSSL 1.0.1 14 Mar 2012

2、问题分析
有问题，多google。

社区给出的解释（https://lists.launchpad.net/openstack/msg12202.html）：
Ubuntu cloud images do not have any ssh HostKey generated inside them (/etc/ssh/ssh_host_{ecdsa,dsa,rsa}_key). The keys are generated by cloud-init after it finds a metadata service. Without a metadata service, they do not get generated. ssh will drop your connections immediately without HostKeys.

看来是因为虚拟机访问169.254.169.254不通造成的。于是到NetworkNode查看下iptables规则。

NetworkNode的nat表规则：

  1. root@network232:~# ip netns exec qrouter-b147a74b-39bb-4c7a-aed5-19cac4c2df13 iptables-save -t nat

可以看到iptables规则没有问题。于是就想着看一下metadata-proxy的日志，果不其然，发现如下打印：
Remote metadata server experienced an internal server error.
接着看metadata agent的日志，同样的，发现如下错误：
content=: 404 Not Found. The resource could not be found.
继续搜索nova-api的日志，找到根源：
ERROR [nova.api.metadata.handler 141] [4541] Failed to get metadata for ip: 192.168.82.232

192.168.82.232是我NetworkNode的IP地址，而metadata应该是从ControllerNode获取啊。于是搜索代码，来到如下地方：
  1. if CONF.service_quantum_metadata_proxy: 

  2. meta_data = self._handle_instance_id_request(req) 

  3. else: 

  4. if req.headers.get('X-Instance-ID'): 

  5. LOG.warn( 

  6. _("X-Instance-ID present in request headers. The " 

  7. "'service_quantum_metadata_proxy' option must be enabled" 

  8. " to process this header.")) 

  9. meta_data = self._handle_remote_ip_request(req)
复制代码
发现进入了else分支，而与Quantum metadata配合时应该是进入if，于是搜索配置项service_quantum_metadata_proxy，发现默认配置为False，而在/etc/nova/nova.conf中并没有进行覆盖，所以导致问题出现。

至此，问题分析完毕。


3、问题解决

修改/etc/nova/nova.conf中配置项service_quantum_metadata_proxy=True，重启进程。

重启虚拟机，查看其console日志输出：
