[Bug 882178] Re: Change of MAC address hangs boot process for 30-60 seconds

[Stéphane Graber]

If you're using ifupdown and clone the machine, you'll need to remove
the line for the old mac address in /etc/udev/70-persistent-net.rules.

Otherwise when booting the cloned machine, your first network interface
will come up as eth1 and not eth0, making ifupdown wait for eth0 to show
up and timeout after 60s without giving you working network.

This is the expected behaviour, just remember to clean 70-persistent-
net.rules before making your image.

Title:
  Change of MAC address hangs boot process for 30-60 seconds

Status in “ifupdown” package in Ubuntu:
  Invalid

Bug description:
  I'm using Virtualbox with a Ubuntu 11.10 machine, which I cloned in order to do some tests.
  This cloned machine recieved a new MAC address, booting the new machine causes the boot process to hang for 30-60 seconds without actually initializing the network.

  The old interface is still in /etc/udev/70-persistent-net.rules and
  somehow causing the network initialize to hang and eventually fail.
