-QEMU is used for VPP-VM testing enviroment. You need to run qemu-2.2.1 or newer
-in order to Vhos-user support. In CSIT VIRL setup DUT has preinstalled QEMU and
-have small VM image "/var/lib/vm/vhost-nested.img". QEMU binary path must
-be "/opt/qemu/bin/qemu-system-x86_64". You can use following script to replicate
-QEMU setup on DUT "resources/libraries/bash/qemu_build.sh" for local testing,
-out of LF's VM setup. VM image must have installed at least qemu-guest-agent,
-sshd, bridge-utils and VirtIO support. Note that VPP must be installed before
-starting QEMU, because VPP will do the hugepages configuration as part of it's
-installation process. Username/password for the VM must be cisco/cisco and
-NOPASSWD sudo access. The interface naming is based on 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" you must set "TRANSPORT=isa-serial:/dev/ttyS1"
-because ttyS0 is used by serial console and ttyS1 is dedicated for
-qemu-guest-agent in QEMU setup.
-There is python library for QEMU setup, start and some utilities
-"resources/libraries/python/QemuUtils.py" and keyword "Stop and Clear QEMU" for
-teardown in resources/libraries/robot/vm/qemu.robot. "Qemu Start" setup one
-management interface by default. You can add Vhost-user interfaces by
-"Qemu Add Vhost User If" keyword.
-Example usage in robot framework test:
-
-*** Settings ***
-| Resource | resources/libraries/robot/vm/qemu.robot
-
-*** Test Cases ***
-| VM test
-| | [Tags] | VPP_VM_ENV
-| | Qemu Set Node | ${nodes['DUT1']}
-| | Qemu Add Vhost User If | /tmp/vhost_sock
-| | ${vm}= | Set Variable | ${None}
-| | ${vm}= | Qemu Start
-| | [Teardown] | Stop and Clear QEMU | ${dut1} | ${vm}
-
-Note that VPP must be started and configured before starting the VM when using
-Vhost-user interfaces.
