Bug Description

Seems this commit has broken our CI testing, specifically nova-volume: https://github.com/openstack/nova/commit/b02cefe64631d51cebdfb5e3a83d22cdfea3b767

Devstack volume exercise failure at https://jenkins.qa.ubuntu.com/view/Precise%20OpenStack%20Testing/job/precise-openstack-essex-test/391/console

euca-describe-instance shows the volume is the 'creating' state, traceback on nova-volume node shows:

Adam Gandelman (gandelman-a) wrote on 2012-02-25:

It appears this is a packaging issue, as nova-volume.upstart does not create /var/lock/nova like other nova-* jobs. We should check that all nova-* upstart jobs ensure the directory exists, because the commit above adds a periodic task to all nova services that will fail if the directory is non-existent.
