+ Trusty smoke lxc tests appear to hang starting from 20131101 (coincides
with the new trusty kernel Linux version 3.12.0-1-generic) . The issue
occurs on both amd64 and i386 images. When this occurs the vm where the

+ lxc containers get created becomes unresponsive.
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
+ sudo apt-add-repository -y ppa:utah/stable
+ sudo apt-get update
+ sudo apt-get install utah
3. Run the lxc tests using
- sudo utah -r lp:ubuntu-test-cases/server/runlists/lxc.run
+ sudo utah -r lp:ubuntu-test-cases/server/runlists/lxc.run
Looks like the test_lxc_simple test is the one that's causing the hang

Note:
- I tried to reproduce this using a saucy vm host and the tests are not hanging
there. The jenkins jobs in smoke tests are using a precise VM host.
