From what you write it seems that: - your engine has ip 10.10.2.143 - From which ip do you run your browser? - Can this ip connect to engine on port 3128? Perhaps your engine setup already configured iptables (or firewalld) and it is blocking you? You can easily verify at runtime by putting this line on engine: iptables -I INPUT -s xxx.yyy.www.zzz -j ACCEPT where xxx.yyy.www.zzz is the ip of the client from where you run the browser so that you put this accept rule on top of INPUT chain and retry to connect to VM console - Which ip have the hosts where VMs are running? - Is engine (so your proxy in your configuration) capable to reach ip of your hosts on spice ports (5900-..)? ALso see my previous thread here: http://lists.ovirt.org/pipermail/users/2013-December/018554.html and the useful answers. I cannot test your config, because I have no control on my network and network admins only allow 80 and 443 so that they are already taken by engine itself and I can't test putting the proxy on engine itself... HIH anyway, Gianluca
