The following steps were used by Enea to generate the 128T qcow2 image used as the VNF image on NFV Access. Keep in mind a Virtual Machine was used instead of a physical host. Prerequisites: 128T-3.2.7-1.el7.centos.x86_64.iso provided by 128 Technologies. A Linux development host with internet access. A least one of the TAP interfaces connected to a bridge with Internet access. How to create the 128T image for NFV Access: >qemu-img create -f qcow2 128t.qcow2 128G >qemu-system-x86_64 -enable-kvm -m 8G -cpu host -smp cores=3,sockets=1 \ -M q35 -nographic bios /usr/share/qemu/bios.bin -boot order=d,menu=on \ cdrom 128T-3.2.7-1.el7.centos.x86_64.iso \ hdb 128t.qcow2 \ device e1000,netdev=net1,mac=52:52:01:02:03:01 \ netdev tap,id=net1,ifname=tap1,script=no,downscript=no Press the <ENTER> key to begin the installation process. Wait for the distribution and the 128T to install: ------------------------------ 128T Packages Installed Please Remove Install Media, then enter <Yes> to reboot and continue install process <Yes> <No> ------------------------------ Press Yes.
