CentOS on VirtualBox does not show eth0

For some reason when I started my CentOS VirtualBox, I was unable to connect to eth0. When I tried

ifup eth0
I get “Device eth0 does not seem to be present, delaying initialization”

The fix for this issue is to do the following:

1. Remove the kernel’s networking interface rules file so that it can be regenerated
   # rm -f /etc/udev/rules.d/70-persistent-net.rules
2. Restart the VM
   # reboot
3. UPDATE your interface configuration file
   # vim /etc/sysconfig/networking/devices/ifcfg-eth0
   Remove the MACADDR entry or update it to the new MACADDR for the interface (listed in this file: /etc/udev/rules.d/70-persistent-net.rules).
4. Remove the UUID entry
5. Save and exit the file
6. Restart the networking service
   # service network restart
