Adding host connectivity

[jnojr]

I stood up a VM running Ubuntu 12.04 It was configured with one NIC in NAT mode... I had forgotten that NAT mode doesn't let me communicate with my VM. So I shut it down, added a second NIC in host mode, and restarted the VM. eth1 exists, but is not up and has no IP. I believe I did the same thing a while back with a VM running Fedora 18, and it "just worked"... I'm not sure if I've done something incorrectly with VirtualBox, or if there's config I need to do in the VM (this is the first time I've ever touched Ubuntu ).

Most likely, you simply need to configure the interface to use DHCP in the guest. I don't remember if this is automatic post-install on Ubuntu.
