Comment 6 for bug 1593207

The problem is in fuel-menu.

Fuel-menu incorrectly configures something in puppets, so it disables hotplug and doesn't enable back (can be found in /var/log/puppet/fuelmenu-puppet.log)

Docker calls script docker-storage-setup, which in turn runs lvcreate. But lvcreate waits for udev to create devices in /dev (or something else), anyway, hotplug must be enabled for running lvcreate.
