I can not open /dev/tty0.
"DEVICES="c:4:all:rw" does not help.
/dev/tty works, but /dev/tty0 does not.
This is feature? or possible to solve this?
It is Okay to run Apache/Sendmail,
but a bit inconvienient for debugging or development or such purposes.

# cat /dev/tty0

[ If you add "DEVICES=" to vps.conf ]
# cat /dev/tty0
cat: /dev/tty0: No such device
( anyway, you can not access /dev/tty0. Why? This is inevitable feature? )
# ls -la /dev/tty0

Ummm?? Maybe here is the problem? What is ve_is_super()???

I still have not solved this issue.
You change something on /dev/tty[0-9] in a VE?
I guess they are not same as usual ones.
