eth0 not starting on boot after Virtualbox clone

I just find from on other another site, you need to edit the file name 70-persistent-net.rules under /etc/udev/rules.d/ change the MAC address to match with the clone VM virtualbox

so edit two files

1. /etc/udev/rules.d/70-persistent-net.rules
2. /etc/sysconfig/network-scripts/ifcfg-eth0 -- from heavyd

change the MAC address in both files to match with the VM VirtualBox assign if you click on the right click cloneVMvirutalBox=>Setting=>Network=>Adapter 1 tap there is a Advanced will provide the MAC address.

Hope this will help when some one come across this site.

For your this question how enable eth0 on startup?

Open /etc/sysconfig/network-scripts/ifcfg-eth0 file in that

change ONBOOT=no

To

ONBOOT=yes
