lxc smoke tests fail to complete

[Para Siva]

lxc smoke tests fail to complete on saucy starting from 20130613. The tests appear to hang on both amd64 and i386 installations with dmesg showing the following last entries,

[ 1596.341224] type=1400 audit(1371466696.690:23): apparmor="DENIED" operation="mount" info="failed flags match" error=-13 parent=3375 profile="lxc-container-default" name="/var/lib/ureadahead/debugfs/" pid=3414 comm="ureadahead" fstype="debugfs" srcname="none" flags="rw"

[ 1598.395653] lxcbr0: port 1(vethw56WKK) entered disabled state

This issue occurred with the kernel version 3.9.0-5.

Steps to reproduce:
1. Install a default saucy server on a vm (either manually or preseeded default installation) with either i386 or amd64 image using KVM, libvirt
2. Do the following to install utah inside the VM
   sudo apt-add-repository -y ppa:utah/stable
   sudo apt-get update
   sudo apt-get install utah
3. Run the ceph tests using
        sudo utah -r lp:ubuntu-test-cases/server/runlists/lxc.run

The issue does not occur with the image of 20130617, which contains 3.9.0-6-generic kernel. Hence, marking the bug as fixed

Re-opening the bug due to the fact the tests fail intermittently even with 20130617.
