Note that VirtualBox offers several types of virtualized networking 
modes. In NAT mode where it communicates with the IP stack of the host 
maybe this makes sense whereas it doesn't in bridged mode.

If VirtualBox and OpenIndiana did what they promised without hickups I 
wouldn't even need two network interfaces to ensure the operation of the 
system. But when bugs occur we try to get around them until they are 
fixed, and that requires at least some knowledge about the system which 
I'm really happy to have acquired.

I can even see on the activity LEDs on the switch that the VMs' network 
is independent of the hosts network.
