For VNC-Access I have to put the following into "ubuntu.one"?
GRAPHICS = [
type = "vnc",
listen = "1.2.3.4",
port = "5902" ]
How can I check if my machine has a route to access 192.168.122.0/24 associated to virbr0? (I can't login into this machine)
And btw: is there a possibility to change "ubuntu.one" without doing a
resubmit? Because this takes about ten minutes and slows down my PC.
In other words, I'm searching for a way to use the image again that
already has been copied via ssh....
Cheers,
Marco
