I've removed the HWADDR from ifcfg-eth0 and touched /.unconfigured, but when I restart the virtual machine, HWADDR is not added back to the ifcfg-eth0. Is there something else we should be doing?

Did you try this already? http://serverfault.com/q/626889/50647 – Aaron Copley Nov 24 '14 at 18:45

I tried the above link, but it doesn't recreate the HWADDR line. – Benjamin Peikes Nov 24 '14 at 19:11

@MichaelHampton I'm trying to prep a CentOS machine for virtualization. I don't want cloned machines to try using the same hardware address. – Benjamin Peikes Nov 24 '14 at 19:12

1I'm not sure if I experienced that or not.. Most of my VMs only have a single interface, so I have no issue leaving that line out of the config. – Aaron Copley Nov 24 '14 at 20:00

It turns out that HWADDR does not get set automatically. It's only in ifcfg-XXX so you can tie a particular network configuration to a particular card. If you only have one interface, HWADDR is not needed in ifcfg-XXX
