Re: No Internet on Virtual Machine
Does groups typed in an Ubuntu terminal show you being a member of vboxusers group? If not, maybe you need to add yourself to that group for networking to work from a guest OS.
Use your normal password (no characters will appear) when sudo asks for it. You may have to log out of X and back in for the added group to take effect.
sudo gpasswd -a your_ubuntu_username vboxusers
If it is not that, not sure why internet would not be working. Normally virtualbox does NAT for your guest OS, so any networking outside would appear to come from your Ubuntu host IP. Can you ping anything on your LAN (like your router) from the Windows guest?
