My OpenStack version is Juno. I had installed my Openstack and the VM in OpenStack's netwrok is work. VMs can ping outer netwrok like http://google.com. But I have no idea why I can't download anything in outer network.The command (like wget,apt-get update all) can't work.I install Ubuntu 14.04 desktop in the VM. Can anyone help??
