1、問題現象

版本：Grizzly master分支程式碼2013.06.17
部署：三個節點（Controller/Compute + Network + Compute）
使用的映象：precise-server-cloudimg-i386-disk1.img
建立虛擬機器命令：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

虛擬機器ACTIVE之後，可以ping通虛擬機器的fixedip（10.1.1.6）和floatingip（192.150.73.5）。VNC訪問虛擬機器正常，出現登入介面。因為Ubuntu的映象無法使用密碼登入，所以只能通過SSH訪問，這也是建立虛擬機器時指定key_name的原因。

在NetworkNode通過ssh登入虛擬機器失敗：

2、問題分析

有問題，多google。

社群給出的解釋（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.

看來是因為虛擬機器訪問169.254.169.254不通造成的。於是到NetworkNode檢視下iptables規則。

可以看到iptables規則沒有問題。於是就想著看一下metadata-proxy的日誌，果不其然，發現如下列印：
Remote metadata server experienced an internal server error.
接著看metadata agent的日誌，同樣的，發現如下錯誤：
content=: 404 Not Found. The resource could not be found.
繼續搜尋nova-api的日誌，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應該是從ControllerNode獲取啊。於是搜尋程式碼，來到如下地方：
[python] view plaincopyprint?
  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)  
        if CONF.service_quantum_metadata_proxy:
            meta_data = self._handle_instance_id_request(req)
        else:
            if req.headers.get('X-Instance-ID'):
                LOG.warn(
                    _("X-Instance-ID present in request headers. The "
                      "'service_quantum_metadata_proxy' option must be enabled"
                      " to process this header."))
            meta_data = self._handle_remote_ip_request(req)
發現進入了else分支，而與Quantum metadata配合時應該是進入if，於是搜尋配置項service_quantum_metadata_proxy，發現預設配置為False，而在/etc/nova/nova.conf中並沒有進行覆蓋，所以導致問題出現。

至此，問題分析完畢。

3、問題解決

修改/etc/nova/nova.conf中配置項service_quantum_metadata_proxy=True，重啟程序。

重啟虛擬機器，檢視其console日誌輸出：
