Title:
  xen: ease cloning of virtual images by disabling mac address rules

Status in “udev” package in Ubuntu:
  Fix Committed

Bug description:
  Similarly to LP #341006 other hypervisor MAC address prefixes should
  be added to the ignore list.

  Currently (Oneiric), /lib/udev/rules.d/75-persistent-net-
  generator.rules has:

  
  # ignore KVM virtual interfaces
  ENV{MATCHADDR}=="52:54:00:*", GOTO="persistent_net_generator_end"
  # ignore VMWare virtual interfaces
  ENV{MATCHADDR}=="00:0c:29:*|00:50:56:*", GOTO="persistent_net_generator_end"
  # ignore Hyper-V virtual interfaces
  ENV{MATCHADDR}=="00:15:5d:*", GOTO="persistent_net_generator_end"
  # ignore Eucalyptus virtual interfaces
  ENV{MATCHADDR}=="d0:0d:*", GOTO="persistent_net_generator_end"

  this list should be expanded to include:

  00:16:3e:* (xen, default range used in xen3)

  (see, e.g.
    http://www.coffer.com/mac_find/?string=00%3A16%3A3E
  )

  These are not caught by:

  # ignore Xen virtual interfaces
  SUBSYSTEMS=="xen", GOTO="persistent_net_generator_end"

  when on HVM mode without PV drivers, as the device appears as "eth0".

  Ideally this would be fixed from Lucid onwards, but should certainly
  be fixed for Precise.
