When running systemd-nspawn with --private-network, I am getting mount

# systemd-nspawn -M iofabric --as-pid2 --private-users=1379532800:65536 --register=no --private-network
Spawning container iofabric on /var/lib/machines/iofabric.raw.

This is on a (host) system with SELinux disabled.

What do these errors mean?
