Connecting to the ONOS GUI
One way to connect to the ONOS GUI is to run a browser inside the VM. Install a GUI in your VM if you haven't already (sudo apt-get install lxde and reboot), and then run a web browser pointed to the IP address of the ONOS node you want to talk to (for onos1, the default will be http://192.168.123.1:8181/onos/ui ). For the GUI to work well, you will want to make sure you've installed the appropriate VM support tools (such as virtualbox tools or VMware tools) for your virtualization platform.
Another (perhaps more enjoyable) way is to run a browser on your client machine or server where the VM is running, as long as you have connectivity to the VM (make sure you can ping its IP address and/or connect to it using ssh, and make sure that it the ports on your VM aren't being blocked by a firewall.)
By default, onos.py automatically forwards connections to the Mininet VM/server to the appropriate ONOS instance.
| Service | VM port to connect to |
|---|---|
| GUI/REST | 8181 (onos1), 8182 (onos2) ... |
Karaf via ssh | 8101 (onos1), 8102 (onos2) ... |
| OpenFlow | 6653 (onos1), 6654 (onos2) ... |
So if you are using a VM whose IP address is 192.168.x.y, to connect to the GUI on ONOS1, you would use the URL http://192.168.x.y:8181/onos/ui/

You need to use the real, correct IP address for your VM - the address |
If you are using VirtualBox, you will probably need to add a host-only interface to your VM and you may even need to run dhclient to make sure that that interface has an IP address. You can also set up port forwarding on a single interface - in this case you will want to make sure that it is set up for every port you wish to connect to (e.g. 8181 for the GUI on onos1.)
