That is odd. AFAIK lxc-start shouldn't need to connect to anything. At
least not when I tested using containers created by download template.

What is on the container config file? Perhaps there's a hook that calls
those URLs?

Not ubuntu template.

Download template, but then specify parameters to choose whatever
distro/versio you need. Try "/usr/share/lxc/templates/lxc-download --help",
and then specify those parameters to lxc-create after "--" (e.g.
"lxc-create -t download -n blah -- -d ubuntu ...")
