Ubuntu and VMware – Losing your ethernet device when migrating

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).

    for me nothing helped except

    sudo /etc/init.d/udev restart

    sudo /etc/init.d/networking restart

    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.

    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?????

    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.

  22. mischa Said,

    January 9, 2010 @ 2:10 pm

    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
