actually there's no such device in your machine. so you should revise it.

1. Write down the MAC Address

   Device Name     Mac Address        the right Device Name

   eth2 ===> 00:0C:29:80:46:66 ==> eth0

   eth3 ===> 00:0C:29:80:46:70 ==> eth1 

2. Modify the file /etc/udev/rules.d/70-persistent-net.rules , keep the top 2 non-commented lines . 

[root@olinfa961 opt]# cat /etc/udev/rules.d/70-persistent-net.rules 

# 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 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:80:46:66", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x1022:0x2000 (pcnet32)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:80:46:70", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

    3.  Modify the ifcfg-eth0 and ifcfg-eth1 files:

[root@olinfa961 opt]# cd /etc/sysconfig/network-scripts/

[root@olinfa961 network-scripts]# ls

ifcfg-eth0   ifdown-eth   ifdown-ppp     ifup-aliases  ifup-isdn   ifup-routes       net.hotplug

ifcfg-eth1   ifdown-ippp  ifdown-routes  ifup-bnep     ifup-plip   ifup-sit          network-functions

ifcfg-lo     ifdown-ipv6  ifdown-sit     ifup-eth      ifup-plusb  ifup-tunnel       network-functions-ipv6

ifdown       ifdown-isdn  ifdown-tunnel  ifup-ippp     ifup-post   ifup-wireless

ifdown-bnep  ifdown-post  ifup           ifup-ipv6     ifup-ppp    init.ipv6-global

[root@olinfa961 network-scripts]# cat ifcfg-eth0

DEVICE="eth0"

HWADDR="00:0C:29:80:46:66"

NM_CONTROLLED="yes"

ONBOOT="yes"

4. reboot
