I'm running VBox under Mac OS with multiple Linux guests (Redhat). Everything works fine except I want to test dual NICs in one of my guests. I'm using host-only adapters and would like to simulate multiple NICs in the guests. I added the second NIC but it doesn't show up in the OS.

Nothing under /etc/sysconfig/network-scripts/ besides ifcfg-eth0

Describe exactly your VB network configuration. What steps did you take to set up the adapter under Linux? What does ifconfig -a show? – Gilles Feb 29 '12 at 23:41
Adding another interface won't magically create a configuration in /etc/sysconfig/network-scripts. You have to do that yourself. Gilles has already pointed out the correct tool for listing available interfaces. You could also use ip link show, or look in /sys/class/net. – larsks Mar 1 '12 at 2:45
I got it working, I needed another NIC in my host (laptop). I ended up enabling my wifi, that gave me a second NIC inside my guest. – luckytaxi Mar 1 '12 at 18:07
