Mandatory device lost after moving guest OS in virtualbox to new hardware

October 29, 2012

After exporting and importing a linux guest OS from virtual box between two MacBook. I got

  waiting for mandatory devices eth0 __nsc__ 

Solution: cd to the /etc/udev/rules.d directory

grep for the network interface that is missing, eg. grep eth0 *

and comment out all the offending device from the old hardware in file 70-persistent-net.rules.
