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
ifconfig -ashow? – Gilles Feb 29 '12 at 23:41/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 useip link show, or look in/sys/class/net. – larsks Mar 1 '12 at 2:45
