Bug Description

Hi,

 I observed an error in documentation regarding the configuration
 needed to be done on additional compute-nodes in order to allow vnc
 access to instances.
 From what I understood from doc you just have to copy nova.conf on
 additional nodes.
 However there are some changes to made in the nova.conf of the node
 you want to add or the cloud.
The parameters to be changed
 are:--vncserver_proxyclient_address;--vncserver_listen

 If on the cloud master they have the values:
 --vncserver_proxyclient_address=$ip_cloud_master
 --vncserver_listen=$ip_cloud_master

 On the newly added compute node they have to be:
 --vncserver_proxyclient_address=$ip_compute_node
 --vncserver_listen=$ip_compute_node

 From my testing and small understanding ....:) these values are as such:
 -vncserver_listen is the address that you will find in libvirt.xml
 corresponding to the instance started on this server. If you put a
 value different from the ip addresses on this server the instances
 won't come up.
 -vncserver_proxyclient_address is the address that nova-consoleauth
 will associate with the requested token.

 I don't know if I explained clearly enough so I will give an example.
 I have 2 servers in my cloud, node01(master_cloud),
 node02(compute_node). If on node02 the value
 vncserver_proxyclient_address is $ip_cloud_master after I start an
 instance on node02 vnc will direct me to $ip_cloud_master:5900 which
 is an old instance created on node01. If If on node02 the value
 vncserver_proxyclient_address is $ip_compute_node after I start an
 instance on node02 vnc will direct me to $ip_compute_node:5900 which
 is what I am looking for. BINGO!!

 Regards,
 Gabriel

Thanks for your report!

So, I can see the configuration options relatively well explained at:
http://docs.openstack.org/trunk/openstack-compute/admin/content/important-nova-compute-options.html

However, in the actually "installation" part of that document, at:
http://docs.openstack.org/trunk/openstack-compute/admin/content/nova-vncproxy-replaced-with-nova-novncproxy.html

does not really carry this through, and could use some examples.
