I believe you might need a newer systemd or libvirt. Libvirt creates
/dev/ttyN from 1-> number of <console> elements in the XML, and also
makes /dev/console a symlink to /dev/ttyN.
If you see double logins this is a good sign that an agetty has been
started on both /dev/tty1 and /dev/console.
A month or so back we made libvirt set "container_ttys" to list
all /dev/ttyN devices except for /dev/tty1. systemd GIT will
honour this env var when deciding how to spawn agettys on the
/dev/ttyN devices.
That said unless you've done some custom config I'd not expect
an outdated systemd to launch anything on /dev/ttyN devices,
only /dev/console.
