Hello,

I'am trying to install OpenVZ. I patched the kernel and created a 
template. If I try to start the VE the following error is given:

# vzctl start 777 ...
RTNETLINK answers: No such device
vps-net_add ERROR: Unable to add route /sbin/ip route add 192.168.2.50 
dev venet0 src 192.168.2.23


Host System Kernel: Etch 2.6.18.5+openvz

etc/vz/conf/777.conf
...
OSTEMPLATE=debian-4.0
IP_ADDRESS="192.168.2.50"
NAMESERVER="192.168.2.1"

# lsmod | grep vz
vznetdev	 16704	0
vzmon		 40648	1 vznetdev
ipv6		236448	9 vzmon

- ifconfig shows no venet0

# ip link show venet0
1: venet0: <BROADCAST,POINTTOPOINT,NOARP> mtu 1500 qdisc noop
     link/void


Big thanks for Help!

greetings

I guess you simply haven't started vz service, thus venet device is not up
and running in the host system.

try /etc/init.d/vz start
before starting VEs.
Make sure you have also configured /etc/sysctl.conf according to installation HOWTO.

Thanks,
