Anthony,
thank you, I saw that.

I'm working in it and I'll report if I have success.

Anthony, I tried to add this flags there and do some more things but I didn't have sucess yet.


I made a question in launchpad with all my network configurations and my log. Can you see that please?

Thank you.

Here are several flags that you must set on your compute host for a multi host deploy:



:option:`--vncserver_listen` - defaults to 127.0.0.1 This is the address that vncservers will bind, and should be overridden in production deployments as a private address. Applies to libvirt only. For multi-host libvirt deployments this should be set to a host management ip on the same network as the proxies.


:option:`--vncserver_proxyclient_address` - defaults to 127.0.0.1 This is the address of the compute host that nova will instruct proxies to use when connecting to instance vncservers. For all-in-one xen server domU deployments this can be set to 169.254.0.1. For multi-host xen server domU deployments this can be set to a dom0 management ip on the same network as the proxies. For multi-host libvirt deployments this can be set to a host management ip on the same network as the proxies.


:option:`--novncproxy_base_url=[base url for client connections]` - this is the public base url to which clients will connect. "?token=abc" will be added to this url for the purposes of auth. When using the system as described in this document, an appropriate value is "http://$SERVICE_HOST:6080/vnc_auto.html" where SERVICE_HOST is a public hostname.

Suppose you have 2 servers, APISERVER and COMPUTESERVER:
APISERVER:public hostname = my.server.commanagement ip = 192.168.1.1

public ip = 172.24.4.1
COMPUTESERVER:management ip = 192.168.1.2
Your nova.conf con COMPUTESERVER would need the following flags:


novncproxy_base_url=http://my.server.com:6080/vnc_auto.html or novncproxy_base_url=http://172.24.4.1:6080/vnc_auto.html

vncserver_proxyclient_address=192.168.1.2vncserver_listen=192.168.1.2


Note that novncproxy_base_url references a public ip or hostname (so clients can connect), while the other flags use private ips.

Hey guys,
I'm using Dashboard with a nova-compute installed in another machine, but when I try access VNC Console I get the error "failed to connect to server".


Here is the log -> http://pastebin.com/5DZMfiNE


Anyone already saw this trouble?
