Yes, you can use vzctl console $CTID $TTYNUM to get a console for those.
In our recent templates we have getty on tty1 and tty2 configured
(just in case /dev/tty1 is screwed you can have it on /dev/tty2).

We were disabling it before because there was no /dev/tty virtualization 
and getty
processes kept respawning leading to waste of CPU time and some nasty log
messages ("getty respawining too fast, disabling for 5 minutes" or so if 
I remember
correctly). Nowadays there's no need to disable it.
