RDO Stack: Failed connect to server

Issue:

When you create an instance, but cannot connect to the VNC Server because of the error message, "Failed connect to server".

Reason:

Your nova vnc configuration may be mapped to wrong vnc server.

Solution:

1. vi /etc/nova/nova.conf

2. find vncserver_proxyclient_address

3. exam the value is valid and could be reached by your host.

4. Modify it to right server, e.g. 127.0.0.1

5. service openstack-nova-compute restart
