Openstack：Horizo​​n - VM关闭后“无法检索使用信息”错误

时间：2016-12-02 14:15:04

标签： ubuntu virtualbox openstack openstack-nova openstack-horizon

我在Ubuntu 16.04.1 LTS桌面上使用Nova（Compute）将Openstack（Newton）设置为Windows 10主机上的虚拟机来宾（Oracle VM VirtualBox ver.5.1.8）。

安装成功，可以在登录过程后通过http://192.168.56.102/dashboard/（来自主机）访问Horizo​​n，如下图所示。 （也可以通过http://10.0.2.15/dashboard/从访客访问，但此处未显示）

当VM关闭并稍后再次打开时，使用Horizo​​n仪表板对Openstack的访问丢失了。 “错误：无法检索使用信息”显示在仪表板上（如下图右上角所示）。这个问题是一个难题，可以一直复制。

以下是/var/log/apache2/horizo​​n_error.log文件中显示的错误剪辑，当在登录过程后从Horizo​​n的仪表板中选择了Computer-＆gt; Overview选项时（产生上面的图2）。

作为与端点通信时指示的问题的错误。验证VM中的服务端点是否正常，但遗憾的是它不是。

svanan@svanan:~/devstack$ openstack endpoint list
Password: 
Missing parameter(s): 
Set a username with --os-username, OS_USERNAME, or auth.username
Set an authentication URL, with --os-auth-url, OS_AUTH_URL or auth.auth_url

以下是VM关闭之前的原始输出。

在VM上验证了ifconfig，它配置了enp0s3，enp0s8，lo，virbr0接口，除了关闭前的br-ex，如下所示：

br-ex     Link encap:Ethernet  HWaddr 1a:ba:3a:4a:d5:4f  
          inet addr:172.24.4.1  Bcast:0.0.0.0  Mask:255.255.255.0
          inet6 addr: fe80::18ba:3aff:fe4a:d54f/64 Scope:Link
          inet6 addr: 2001:db8::2/64 Scope:Global
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:15 errors:0 dropped:0 overruns:0 frame:0
          TX packets:79 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1 
          RX bytes:776 (776.0 B)  TX bytes:10328 (10.3 KB)

不确定此桥（br-ex）的缺席是否可能是因为Horizo​​n（来自主机）无法与Guest中的服务连接。尝试在etc / network / interfaces中静态配置如下，以获得相同的br-ex输出。

auto br-ex
  iface br-ex inet static
  hwaddress 1a:ba:3a:4a:d5:4f
  address 172.24.4.1
  broadcast 0.0.0.0
  netmask 255.255.255.0

  iface br-ex inet6 static
  pre-up modprobe ipv6
  address 2001:db8::2
  netmask 64

我得到的br-ex输出

svanan@svanan:~$ sudo systemctl restart networking
svanan@svanan:~$ ifconfig

br-ex     Link encap:Ethernet  HWaddr 7a:07:1d:1d:1a:40  
          inet addr:172.24.4.1  Bcast:0.0.0.0  Mask:255.255.255.0
          inet6 addr: fe80::18ba:3aff:fe4a:d54f/64 Scope:Link
          inet6 addr: 2001:db8::2/64 Scope:Global
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:126 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1 
          RX bytes:0 (0.0 B)  TX bytes:19334 (19.3 KB)

从上面可以看出，我无法将HWaddr配置为1a：ba：3a：4a：d5：4f而不是7a：07：1d：1d：1a：40出现。

问题：

  1. 在VM关闭并打开序列之后，是否可以忽略br-ex可能是Horizo​​n无法从其服务中检索信息的原因。
  2. 如何将HWaddr静态设置为1a：ba：3a：4a：d5：4f for br-ex？语法hwaddress 1a：ba：3a：4a：d5：4f似乎不起作用。
  3. 如果您遇到类似的问题，可以分享一下您是如何解决的。
    4. 如果{{3这种方法需要很长时间，如下所示，

    希望你能协助指导我。感谢。
