[one-users] OpenNebula 3.0 RC1 NoVNC problems

Tue Sep 27 13:24:53 PDT 2011

Hi, Hector.

Without changes, noVNC has began to work now for KVM VM instances. :O...

However, it seems to work only if we browse with Firefox/Chrome using 
internal IP address of Sunstone Server. If we use NAT forwarding of SSL 
port from the public IP to the SSL port of Lighttpd which connects 
locally to sunstone web server, we are able to manage OpenNebula site 
but noVNC client does not work.

Of course, we miss something, but can you please give me some clues to 
use noVNC from external/public side over SSL without using OpenVPN or 
similar?. Is this scenario supported?

Best Regards and thank you for your time,
Alberto
