I got this error:

#sudo vzctl enter 403
enter into CT 403 failed
Unable to open pty: No such file or directory

I tried these commands with no luck:

#sudo vzctl exec 403 update-rc.d -f udev remove
#sudo vzctl restart 403

Also this:

#sudo vzctl exec 403 /sbin/MAKEDEV tty
bash: /sbin/MAKEDEV: /bin/sh: bad interpreter: No such file or directory


Why is that?
