Try to start Eth0 device
# ifup eth0 Device eth0 does not seem to be present, delaying initialisation
To Solve this :
Delete networking interface rules file so that it can be regenerated and reboot your Redhat system.
# rm /etc/udev/rules.d/70-persistent-net.rules # reboot
New Mac address has been generated:
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:fe:c1:03", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
Again you try to start.
ifup eth0
