Yup, I get it too. For the bridged connection to work, the guest needs a DHCP address from the same DHCP server as the host. Your gateway can dole out an address to each. In my case, Adelphia will only give me one address- already assigned to my host OS.
I still can't get the host-only connection to work. I can ping the VM from Windows, but I can't establish an http connection. I'm still combing through the docs...
