Looking at this, it looks like an apparmor issue. udev isn't related at
all with building up network connections.

Title:
  networking does not come up in cloud image on hyper-v

Status in “linux” package in Ubuntu:
  Incomplete
Status in “udev” package in Ubuntu:
  Invalid

Bug description:
  Hi,
    Upon testing ubuntu cloud images on Hyper-v and openstack, we found that 12.04 images seem to work fine.
    However, the 13.10 saucy images are not working properly.  The network interface doesn't seem to come up.

  It would appear that the network interface isn't functioning properly,
  and apparently 'ifup' after logging in correctly brought it up. so
  possibly something racy on early boot bringup.
