This is intentional, and also a bug. libguestfs-live currently has a limit of one user at a time. We normally run it from systemd which restarts guestfsd after each user. See: http://pkgs.fedoraproject.org/cgit/libguestfs.git/tree/guestfsd.service The limit of one user at a time makes sense for regular libguestfs, but not so much for libguestfs-live, where we could easily support multiple parallel users. However the reason we don't support that is because we have only one virtio-serial channel with a fixed name (/dev/virtio-ports/org.libguestfs.channel.0). virtio-serial channels are not multiplexed, and they have to be created in advance [AFAIK -- is this still true?] so you would always have a very awkward situation where max N users are supported concurrently (at the moment, N=1). Assuming we stick with virtio-serial for the libguestfs-live case and don't use something more normal like TCP/IP. So that's why this is also a bug. Fixing it isn't too hard TBH, but no one cares enough about this use-case to have sent any patches so far.
