Hi, I see that the minimum kernel version required for ubuntu 14.04 is 4.2 [1]. The precheck job failed on gate because those ubuntu VMs have kernel version 3.13. Shall we add kernel upgrade command (i.e., apt-get install linux-image-generic-lts-wily) in the precheck role? - Hui [1] http://docs.openstack.org/developer/kolla/quickstart.html#installing-dependencies [2] http://logs.openstack.org/19/313819/1/check/gate-kolla-dsvm-deploy-ubuntu-source/f49ad57/console.html#_2016-05-08_02_31_50_295
