vnc is supported by qemu, so we needn't to install a vnc-server into instance.
you may check the vnc connection by connecting it directly on the host by a vnc
client,
1. virsh dumpxml ${instance-uuid}
2. get the vnc port: like 5900 or 59XX
3. get the vnc bind address: like 127.0.0.1 or 0.0.0.0(same as the
vncserver_listen = 127.0.0.1 in nova.conf)
4. make a port forwarding to the host by ssh and set the proxy in vnc client if
your vncserver_listen = 127.0.0.1
5. set the target ip address to the host of instance and the vnc port 59XX to
the vnc client and connect to the instance
<graphics type='vnc' port='5900' autoport='yes' listen='127.0.0.1'
keymap='en-us'>
<listen type='address' address='127.0.0.1'/>
</graphics>
if this is ok, then may be the vncproxy type you config is wrong, there are two
types :'novnc' and 'xvpvnc', and in my env, the 'novnc' is used,
the novnc service need be installed on the host,
then you can get the vnc-console by 'nova get-vnc-console ${instance-uuid}
novnc',
hzwangpan@myhost:~$ nova get-vnc-console e4975b9f-95d0-4223-8df9-7d4f017b5de7
novnc
+-------+-------------------------------------------------------------------------------------+
| Type | Url
|
+-------+-------------------------------------------------------------------------------------+
| novnc |
http://xxx.xxx.xxx.xxx:6080/vnc_auto.html?token=45fc8fc6-4488-4b4f-9b20-53de67d9ef8d
|
+-------+-------------------------------------------------------------------------------------+
the ip of Url is same as the config novncproxy_base_url =
http://xxx.xxx.xxx.xxx:6080/vnc_auto.html in the nova.conf.
then you can try to open the url in the browser like google chrome of
firefox(html5/websocket should be supported).
the vnc console will be open if there is no error.
