man tty(4) says: 

	It is a  synonym for the controlling terminal of a process, if any.

so whether the process is in the host or in a container, /dev/tty will
is just the process's own controlling terminal right ? Two processes each
writing to "/dev/tty" would very well be writing to different terminals.

So, I don't see why it needs to be virtualized. Besides, linking /dev/tty1
to /dev/tty would not be the right I think.
