Public bug reported: Trusty smoke lxc tests appear to hang starting from 20131102 (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 when this happens.
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 lxc tests using 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 and soon after http://bazaar.launchpad.net/~ubuntu-server-dev/ubuntu- test-cases/server-tests- raring/view/head:/testsuites/lxc/test_lxc_simple/lxctest.py#L193 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.
