Well, I try to ...

I created the needed /dev/ttyp0 and /dev/ttyp0 by hand 
in /vz/private/<id>/dev/ and mount also /proc by hand. Then it is possible to 
enter the gentoo-VPS:

gs ~ # vzctl enter 2001
entered into VPS 2001
ovz01 / # ps aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         1  0.0  0.1   1368   480 ?        Ss   17:06   0:00 ini
root     14644  0.0  0.3   1740   780 ?        Ss   17:14   0:00 vzctl: ttyp0
root     15669  0.5  0.5   2244  1288 ttyp0    Ss   17:14   0:00 bash -i
root     15671  0.0  0.3   2376   836 ttyp0    R+   17:14   0:00 ps aux
ovz01 / #      

I also copied /etc/init.d/net.lo to the VPS and some additional scripts, which 
are apparently missing.
But in the gentoo-VPS I get still:

ovz01 / # /etc/init.d/net.venet0 start
 * Starting
 *       no interface module has been loaded
ovz01 / #  
ovz01 / # /sbin/ifconfig -a

ovz01 / #                            

If I try that with a debian-guest on the gentoo-host, I get:

gs ~ # vzctl enter 2002
entered into VPS 2002
root at ovz02:/# ifconfig -a
lo        Link encap:Local Loopback
          LOOPBACK  MTU:16436  Metric:1

venet0:0  Link encap:UNSPEC  HWaddr

root at ovz02:/#    

So the interface venet0:0 is missing in the gentoo-guest.
