I am running an Ubuntu 8.04 64 bit
# uname -a
2.6.24-24-openvz
The server has a public IP address and name, and has
internet connectivity(I configure it through ssh).
The problem is that I can't get networking to work inside
a new VE, for example the precreated ubuntu-8.04-x86
vzctl create 777 --ostemplate ubuntu-8.04-x86
vzctl start 777
vzctl set 777 --ip 193.*.*.* --hostname mydomain.anotherdomain.com --nameserver 193.x.y.z --save
The ifconfig outside the ve:

The sysctl.conf
# On Hardware Node we generally need
# packet forwarding enabled and proxy arp disabled
net.ipv4.conf.default.forwarding=1
net.ipv4.conf.default.proxy_arp=1
net.ipv4.ip_forward=1
# Enables source route verification
net.ipv4.conf.all.rp_filter = 1
# Enables the magic-sysrq key
kernel.sysrq = 1
# TCP Explict Congestion Notification
#net.ipv4.tcp_ecn = 0
# we do not want all our interfaces to send redirects
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
Inside the VE there is no internet.
Any sugestions of what to do more ?
