+repository contains a set of scripts to prepare `Built-root
+<https://buildroot.org/>`_ based embedded Linux image with all the
+dependencies needed to run DPDK Testpmd, DPDK L3Fwd, Linux bridge or
+Linux IPv4 forwarding.
+
+Built-root was chosen for a VM image to make it lightweight and with
+fast booting time to limit impact on tests duration.
+
+In order to execute CSIT tests, VM image must have following software
+installed: qemu-guest-agent, sshd, bridge-utils, VirtIO support and DPDK
+Testpmd/L3fwd applications. Username/password for the VM must be
+``cisco``/``cisco`` and ``NOPASSWD`` sudo access. The interface naming
+is based on the driver (management interface type is Intel E1000), all
+E1000 interfaces will be named ``mgmt<n>`` and all VirtIO interfaces
+will be named ``virtio<n>``. In VM ``/etc/init.d/qemu-guest-agent`` must
+be set to ``TRANSPORT=isa-serial:/dev/ttyS1`` because ttyS0 is used by
