FYI I have succesfully run systemd in libvirt LXC with all namespaces except for the user namespace. https://www.berrange.com/posts/2013/08/12/running-a-full-fedora-os-inside-a-libvirt-lxc-guest/ I have not tried to use user namespaces yet, but I wouldn't anticipate any problems. The key tasks is that after running the 'yum' command to populate the chroot with an install of the OS, you need to have a script that changes all the user / group IDs. eg in the libvirt XML you're going to setup a UID/GID mapping so that uid 0 in the container maps to say uid 500 in the host, and so on for any other uids. You need to setup your chroot files to have this matching ownership. At some point we need to create the 'virt-bootstrap' command I mention in that blog post todo this uid mapping automatically with user namespaces.
