if you clone a VM, you may see an error like
“Device eth0 has different MAC address than expected, ignoring”
Simply edit /etc/sysconfig/network-scripts/ifcfg-eth0 script, and remove the HWADDR line, then restart networking ( /etc/init.d/network restart ).
If you ever happen to be building python from source, and at the end of your make, you notice a message along the lines of
“failed to find the necessary bits”
It’s only a warning about some apperantly optional modules; you should still go ahead and issue a “make test”, see how you feel then, before starting the hair-pulling.
