VirtualBox

Configure Network

1. set network mode to "Bridged Adapter"

2. set proxy in Ubuntu system

   http_proxy='http://proxy_username:password@proxy_ip:port'
   https_proxy='https://proxy_username:password@proxy_ip:port'
   ftp_proxy='ftp://proxy_username:password@proxy_ip:port'

   add above configuration to /etc/environment to load them automatically at login (or system start - I might look that up if it matters).

Install VBoxGuestAdditions.iso

Install VBoxGuestAdditions.iso into Ubuntu Server version
