I’ve found that it’s a lot easier to just delete 70-persistant-net.rules and then reboot the newly-cloned machine. Ubuntu will recreate the file with no problem.

I think this may also help if you transfer a VM from OSX fusion to windows VMware player. I haven’t testing it yet, but I had trouble with eth0 when trying an debian VM on windows.

@SonniesEdge: Thanks I’ve updated the post

@AlastairC: Yep indeed this does work for VMWare Fusion I’ve jsut had exactly that error with Debian.

Thanks! Saved me a lot of trouble. I had the same problem after cloning one machine.

You’re a lifesaver.

Thanks a bunch. Great and precise post that saved me a lot of trouble. I encountered this problem after moving a Virtual Machine from a Windows VMWARE Server 2 environment to a Ubuntu Linux environment.

Any tips on what to do if you remove/move the file and it does NOT rebuild it?

In my case, I installed a new VA-LAMP from virtualappliances.net. I did some config and customization
- installed rcconf
- disabled apache, lighthttpd, mysql, php
- changed root password
- shutdown

then I used vmware converter to create a new .OVF locally on my PC. Then I used vmware converter to re-upload the .OVF and create a new image with a new name.

now there’s no eth0. I tried uninstalling/reinstalling vmware tools, removing the persistent-net.rules file, rebooting, removing and re-adding the network card from ESXi and I still can’t get any network on the box.

dmesg shows no eth0 or eth1 lines.

I wonder if it’s a MAC address problem because it came from and went to the same ESXi box, but I’m not sure how to troubleshoot that.

This really helped me! Thanks thousandtimes. For others, my configuration: Windows XP running on AMD Athlon 64, Ubuntu server 7.10 running on vmware player.
