Hi,
I have setup VirtualBox, and set up its bridged networking. The weird part is that somehow the bridge and my eth0 (sky2) were not being brought up on system start! I thought maybe it was NetworkManager weirdness, so I disabled that service. Now here is what happens:

- Upon system start, I only get the following NICs: lo, vbox0
- If I immediately issue a "service network restart", I get the following NICs: eth0, vboxbr0, vbox0, lo

Obviously, since nothing changed that a possible bug! Here are my relevant ifcfg files

[root@magic1 network-scripts]# cat ifcfg-eth0
