[Bug 1099278] Re: Network devices with a MAC with prefix 2c:c2:60 should not be have a persistent rule

[Boris Figovsky]

I have tested version 175-0ubuntu9.3 from precise-proposed.
The test was:
1) Boot the latest release of Ubuntu Precise Cloud-image (http://cloud-images.ubuntu.com/releases/precise/release/ubuntu-12.04-server-cloudimg-amd64-disk1.img) using my preferred virtualization technology, while specifying a random MAC of the form 2c:c2:60:XX:XX:XX;
2) Clean-up /etc/udev/rules.d/70-persistent-net.rules
3) Install proposed udev package
4) Reboot the guest
5) Verify that /etc/udev/rules.d/70-persistent-net.rules is clean

Note: due to https://bugs.launchpad.net/ubuntu/+source/udev/+bug/381104,
I could not install proposed package inside the guest using chroot (so I
do not have to boot it).

Title:
  Network devices with a MAC with prefix 2c:c2:60 should not be have a
  persistent rule

Status in “udev” package in Ubuntu:
  Fix Released
Status in “udev” source package in Precise:
  Fix Committed

Bug description:
  [Test Case]
  1) using your preferred virtualization technology create an Ubuntu guest with a MAC address starting with 2c:c2:60.
  2) boot the Ubuntu guest
  3) cat /etc/udev/rules.d/70-persistent-net.rules

  The file will contain a line with an address containing "2c:c2:60".
  With the version of the package from -proposed it will not.

  [Regression Potential]
  Low as this is limited to MAC address assigned to Ravello Systems.

  The MAC prefix 2c:c2:60 should be treated like 52:54:00 (KVM) and 00:0c:29 VMWare (VMWare):
  network devices with a MAC that starts with 2c:c2:60 shall not be persistent.

  This MAC prefix belongs to Ravello Systems:

  A patch to Precise's version of udev is attached.
