How to share internet connection on Mac OS X to Virtualbox vm’s using Host-only

  • 772

In one line : is the following possible : Airport <- "OS X bridge" -> vbox-Host-only -> vm's

Virtualbox (3.1.4) setup :

  • Host : Mac OS X 10.5
  • Guest : Ubuntu Linux
    • adapter1 - Bridged (en1: Airport) : To give the vm access to internet and communicate when Airport is connected
    • adapter2 - Host-Only (vboxnet0) : To enable host/guest communication when Airport is not connected

I'd like to make it simpler and only keep adapter 2 (host-only) and relying on OS X connection sharing/bridging I thought i could just keep the Host only configuration, and on the host go to internet sharing and select "share from airport" to vboxnet0 . Only to find out that vbox's virtual interface doesn't appear in the interfaces list on OS X preferences.

I know that on a linux host you could install something called bridge-utils and use that to bridge the two insterfaces. Is there any thing like that for Mac ?

  1. Doesn't Virtualbox have a third kind of interface, an automatic NAT interface, like VMware does? if so, replace the two interfaces with a single NAT interface and all should be good...

  2. If you have two system guest attached on Mac os x host and assign them the NAT, the guest systems will have same IP address.
