Hello!
Host OS: Centos 5.4, VPS OS: Ubuntu 9.10.
I can't ping google.com on my VPS.
I used default Ubuntu template from this site, google nameserver 8.8.8.8 for VPS and ip 174.142.167.217.
vzctl create 217 --ostemplate ubuntu-9.10-x86 --ipadd 174.142.167.217 --hostname database.entropia.us --name database
vzctl set 217 --onboot yes --nameserver 8.8.8.8 --save
I need install public VEs (with their own IP addresses) so I'm look at http://wiki.openvz.org/Common_Networking_HOWTOs and use this command:
[host-node]# echo 1 > /proc/sys/net/ipv4/ip_forward
ifconfig on my host system:

next i start and enter to my VPS and see ifconfig command blank result..
Info from datacenter:
Primary IP address : 67.205.67.10
Primary IP mask : 255.255.255.224
Gateway : 67.205.67.1
Usable secondary addresses: 174.142.167.217-222
Mask : 255.255.255.248
So also I replaced all 255.255.255.255 in /etc/vz/dists/scripts/debian-add_ip.sh to 255.255.255.248 in debian add ip script...
P.S.
[root@cl-t127-072cl ~]# ip rule list
0: from all lookup 255
32766: from all lookup main
32767: from all lookup default
[root@cl-t127-072cl ~]# iptables -t nat -L && iptables -t filter -L && iptables -t mangle -L
