QEMU device setup

LAVA can use qemu as a DUT and run test inside QEMU.

Create device-type

Create a device-type in the admin interface.

The only relevant information is the device-type name that should be qemu.

Command line

lavaclilava-server

lavacli device-types add qemu

lava-server manage device-types add qemu

Create device

Create a qemu device in the admin interface:

• hostname: name of the device
• device-type: qemu
• worker host: worker that will run the job

Command line

lavaclilava-server

lavacli devices add --type qemu --worker <worker> <hostname>

lava-server manage devices add \
    --device-type qemu \
    --worker <worker> \
    <hostname>

Device configuration

In order to submit jobs to the newly created device, LAVA requires a device dictionary. For a simple qemu job, this device dictionary would work:

{% extends "qemu.jinja2" %}

{% set netdevice = "user" %}
{% set memory = 1024 %}

This file should be pushed to the LAVA server under /etc/lava-server/dispatcher-config/devices/<hostname>.jinja2.

Command line

lavaclilava-server

lavacli devices dict set <hostname> <filename>

cp <filename> /etc/lava-server/dispatcher-config/devices/<hostname>.jinja2
chown lavaserver:lavaserver /etc/lava-server/dispatcher-config/devices/<hostname>.jinja2

Activate the device

By default, a new device is put in maintenance.

As the device is now configure, admins can put it online in the device page.

Command line

lavaclilava-server

lavacli devices update --health UNKNOWN <hostname>

lava-server manage devices update --health UNKNOWN <hostname>
