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.
