libguestfs does not work on ubuntu because the kernel is not world readable. This breaks file injection with libvirt. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/759725 for more details. The workaround proposed by Ubuntu is to relax the kernel ACL if needed, so we need to do that in case file injection is enabled on an Ubuntu host running libvirt.
