Virtualbox on Ubuntu Host: Access guests by hostname

view story

http://askubuntu.com – I have several virtualbox applicances (windows, linux) each of them configured with two network adapters: NAT for acessing the internet host-only for hosts <> hosts and hosts <> guest communication Problem is, I can conly communicate by ip address. I want to communicate by hostname, ie, I want to be able to reach any host from any other host (or guest) by using the hostname. Is this possible? I already have a host-only adapter (vboxnet0) on the host machine, and networking is fine, but I would like to avoid assigning static ips to each appliance. (HowTos)
