I am instaling Fedora 15, on Mac OS X Lion Server, Virtual Box Following document http://www.howtoforge.com/perfect-server-fedora-15-x86_64-ispconfig-3 4 Change Name Of Your NIC To ethx ================================= This step did not work for me: vi /etc/grub.conf ... and add biosdevname=0 to the kernel line: and reboot. So I had to also do this mv /etc/sysconfig/network-scripts/ifcfg-p2p1 /etc/sysconfig/network-scripts/ifcfg-eth0 and change all the p2p1 (or whatever) to eth0 (or whatever) vi /etc/sysconfig/network-scripts/ifcfg-eth0 vi /etc/udev/rules.d/70-persistent-net.rules reboot
