Today I was making a couple of Clone on VMWare workstation and I got below error after cloned machine was started. as result I didn't have eth0 !
[root@mysql1 ~]#service network restart
Shutting down loopback interface: [ OK ]
Bring up loopback interface: [ OK ]
Bring up interface eth0: Device eth0 doesnt seem to be present, delaying initiatlation [ FAILED ]
So I ran :
[root@mysql1 ~]# dmesg |grep eth
e1000 0000:02:00.0: eth0: (PCI:66MHz:32-bit) 00:0c:29:9e:b4:54
e1000 0000:02:00.0: eth0: Intel(R) PRO/1000 Network Connection
udev: renamed network interface eth0 to eth1
and remove old Ethernet and rename back the new ethernet to eth0
note that I removed the first two lines below with has eth0 and renamed eth1 to eth0
the 00:0c:29:91:f2:83 is actually old MAC address from the source machine that we don't need and 00:0c:29:9e:b5:54 is the new MAC address.
before:
after:
after this you need to edit: /etc/sysconfig/networking/devices/ifcfg-eth0 and
change the :
HWADDR=[old mac address]
to
HWADDR=[new mac address]
After this you must reboot your system to get new hardware settings in place

udev: renamed network interface eth0 to eth1
there it was the issue that my eth got renamed, the solution is to edit:
/etc/udev/rules.d/70-persistent-net.rules
/etc/udev/rules.d/70-persistent-net.rules
and remove old Ethernet and rename back the new ethernet to eth0
note that I removed the first two lines below with has eth0 and renamed eth1 to eth0
