I've searched all over the net and found an interesting post about it on No internet connection on Virtualbox (Windows 7 as guest, ubuntu 13.04 as host). But unfortunately this did not work for VirtualBox Version 5.0.20 r106931. It worked before but suddenly the Internet stopped working :( I only have eth0 as Bridged Adapter and i used the HWaddr value from ifconfig for the MAC address. Please help... maybe it has something to do with my purging off the "unity" desktop environment and installing the xfce xubuntu desktop environment.

  • You have internet on Ubuntu (host) but not on your Window 7 (guest)?
