CentOS 7 network doesn’t work on vzLinux (OpenVZ) VPS

A missing directive ( ARPCHECK=\”no\” ) in ( /etc/vz/dists/scripts/redhat-add_ip.sh ) causes this.

In the hypervisor edit /etc/vz/dists/scripts/redhat-add_ip.sh

function create_config()

{

……

        echo “DEVICE=${VENET_DEV}:${ifnum}

ONBOOT=yes

ARPCHECK=\”no\”

IPADDR=${ip}

…….

}
