VMWare bases the MAC address of interface on it’s internal UUID. If you shift a machine (copy, rename) vmware asks to update the UUID. You might get something like this:
# ifup eth0
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFADDR: No such device
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
eth0: ERROR while getting interface flags: No such device
The solution found by hbraga is to check /etc/iftab. Ubuntu on install adds the MAC address for each interface to this file. Either comment out the lines or update them to reflect the correct details.

In Debian Etch, it seems to get confused in a similar way.
The solution is slightly different though – you need to remove the old MAC address entry in
/etc/udev/rules.d/z25_persistent-net.rules
and change the entry for the new MAC address to use eth0 (in my case it became eth1).
Thank you (both), it solved my problem!

thnks a lot Mark
i’ve a similar issue with my debian-VM (in virtualbox) after moving it to another host
and solved editing /etc/udev/rules.d/z25_persistent-net.rules
for me nothing helped except
sudo /etc/init.d/udev restart
sudo /etc/init.d/networking restart
this on 8.04
This bug [1] ticket has some detail about the fix as well.

Thanks.
Your post saved my day!
Simplest solution:
1. edit /etc/network/interfaces and change eth0 to eth1
2. reboot
3. VMWare will auto-generate a new virtual hardware NIC and Linux will auto-configure it.
Tnx a lot! I was struggling for an hour or so.. while the fix was only 30 secs
Editing /etc/udev/rules.d/70-persistent-net.rules in 8.10 worked wonders. I had to update my DHCP Reservation on the network with the new MAC Address, but that’s beside the point.
if you have the new virtualbox, you can set the mac address also in the VM settings of the VM in virtualbox.
so i changed the mac address there instead of inside the VM
thanks!
Thx Alex, that works!
THANKS for that!!!! Was in urgent problems and this solved it!
On ubuntu 10.04, removing lines in /etc/udev/rules.d/70-persistent-net.rules and restarting computer saved me.
Thx all for this kind of support o/
yes it worked for me as well.
This was by far the easiest solution to implement. Even the biggest N00b could do it. Thanks. Is there any way to move this solution to the top of the page?????
Thanks! My /etc/udev/rules.d/70-persistent-net.rules had more lines for same network adapter. I deleted wrong lines, rewrite NAME and reboot.
Below solution worked for me too on server 10.04
