--------------------------------------------------------------

I'm having the same issue. I checked the Mesos source code and a kernel patch is also required. This must be the four kernel patches mentioned on this page: http://mesos.apache.org/documentation/latest/network-monitoring/

Mesos source code:

  // Set the MAC address of the host loopback interface (lo) so that
  // it matches that of the host public interface (eth0).  A fairly
  // recent kernel patch is needed for this operation to succeed:
  // https://git.kernel.org/cgit/linux/kernel/git/davem/net.git/:
  // 25f929fbff0d1bcebf2e92656d33025cd330cbf8
  Try<bool> setHostLoMAC = link::setMAC(lo.get(), hostMAC.get());
  if (setHostLoMAC.isError()) {
    return Error(
        "Failed to set the MAC address of " + lo.get() +
        ": " + setHostLoMAC.error());
  }
