Hello!
I try to migrate real server with CentOS 5.6 to VPS following
wiki.openvz.org/Physical_to_container and wiki.openvz.org/Creating_a_CentOS_5.0_Template for instructions, but no active network is running. ifconfig not show any devices
the problem is same as the problem in my post about Mandriva VPS creating
P.S.
# service network restart # return:
# service network restart
Shutting down loopback interface: [ OK ]
SIOCGIFFLAGS: No such device
Bringing up loopback interface: Device lo does not seem to be present, delaying initialization.
[FAILED]
Bringing up interface venet0: Device venet0 does not seem to be present, delaying initialization.
[FAILED]

Yes. CentosOS, Slackware, Mandriva

2. What is the output of the following commands (inside your failing CT)?
/sbin/ip r
/sbin/ip a
ifconfig -a
ls -l /etc/sysconfig/network-scripts/
