Well,

(1) Despite the comments in the above bug report, networking scripts 
have nothing to do with vzctl enter
(2) vzctl enter uses either /dev/ptmx and mounted /dev/pts, or older 
/dev/ttyp* + /dev/ptyp*. Check those devices exist in CT, check that 
/dev/pts is mounted.
(3) You can easily fix both from the host system.

For new devices:
# cp -a /dev/ptmx /vz/root/123/dev/
# vzctl exec 123 grep pts /proc/mounts # Check if the mount is there
# vzctl exec 123 mount -t devpts devpts /dev/pts # Mount if necessary

For old devices:
# cp -a /dev/ttyp* /dev/ptyp* /vz/root/123/dev/

(4) There's an extensive wiki page devoted to the issue:

Hope that helps
