Hello,
We upgrade from LAVA 2019.04 to 2019.10 and we have issues with the prompt matching when the device boots.
We test 2 kinds of Linux images:
* Development image
* it outputs data into the serial (secure boot, uboot, kernel, systemd)
* user: root, pass: empty
* Production image
* it doesn't output anything and *only presents the login prompt*
* user: root, pass: it could be anything
The workflow is the following:
* spin up LXC container for recovery mode
* boot the DUT waiting for the prompt. We don't need to login using the serial connection but we need to wait the prompt to understand that the board has successfully booted
* run tests from the LXC container and using ssh to the DUT
In LAVA 2019.04 everything was working as expected:
...
start: 7.3 auto-login-action (timeout 00:05:57) [target]
Using line separator: #'\n'#
No login prompt set.

While in 2019.10 the job is failing with the following:

Another thing we observed in LAVA 2019.10: using the dev images (hence with output data) it works without any problem.
Here a snippet of our pipeline:
....
- boot:
namespace: recovery
timeout:
minutes: 5
method: recovery
commands: recovery
- deploy:
timeout:
minutes: 10
to: recovery
namespace: recovery
connection: lxc
images:
images to download.....
os: debian
- test:
namespace: lxc
connection: lxc
timeout:
minutes: 10
definitions:
- from: inline
name: flash-image
path: inline/flash-image.yaml
repository:
metadata:
format: Lava-Test Test Definition 1.0
name: flash-image
description: "Flash image to board in recovery mode"
os:
- oe
run:
steps:
- steps to recover the board
- boot:
namespace: recovery
timeout:
minutes: 5
method: recovery
commands: exit
- boot:
namespace: target
method: minimal
failure_retry: 3
prompts:
- "mbed-linux-os-(.*) login:"
timeout:
minutes: 6
....
Looking at the LAVA code we think the following commit changed the behaviour: https://git.lavasoftware.org/lava/lava/commit/6b5698a2d3ed23031e40aa1d86181…
How are we supposed to change the pipeline to make it work again?
Thanks

All,
I'm testing some feature about associated log lines in lava, job.yaml is as follows.
Job.yaml:
- test:
connection: lxc
definitions:
- from: inline
name: my_suite
path: me.yml
repository:
metadata:
format: Lava-Test Test Definition 1.0
name: smoke-case-run
description: Run smoke case
run:
steps:
- lava-test-case "Case001" --shell 'echo wow'
- lava-test-case "Case002" --shell 'ls'
namespace: lxcEnv
timeout:
minutes: 10
1. Then, let's see next picture of Case001:
[cid:image002.jpg@01D59322.5F8C2990]
it said startline=153, lastline=154, that's next:
Line153 is "Received signal: <STARTTC> Case001", Line 154 is "Received signal: <ENDTC> Case001".
You could see in fact the log "wow" not in the 2 lines.
[cid:image008.jpg@01D59322.5F8C2990]
2. let's see next picture of Case002:
[cid:image009.jpg@01D59322.5F8C2990]
It said startline=160, lastline=163, that's next:
[cid:image010.jpg@01D59322.5F8C2990]
It's ok, that between Ln160 & Ln163 I got the output of `ls`.
What happened for "Case001"? The startline & endline not correct. It seems if I directly do "echo", the info is wrong. while "execute command", the info is correct.
Of course my case will not just do "echo", just I want to know if any risk for me to fetch the wrong START/LAST lines in other scenario? (I will use script to fetch it with xmlrpc).
Hi,
When test job uses boot action with method: u-boot there was an option
to tell it which boot command to call in u-boot shell. This was done
using 'type' parameter. Example from docs:
- boot:
method: u-boot
commands: nfs
type: bootz
prompts:
- 'root@debian:~#'
This parameter was deprecated for more than a year. I just submitted a
patch to remove this feature. If you're using it, please consider
changing to setup where kernel image type is set using deploy section.
Example:
- deploy:
timeout:
minutes: 4
to: tftp
os: oe
kernel:
url: 'https://example.com/zImage'
type: 'zimage'
dtb:
url: 'https://example.com/dtb.dtb'
nfsrootfs:
url: 'https://example.com/rootfs.tar.xz'
compression: xz

Does lava has roadmap to separate resource management to some open source mechenisim, so it could share resource with other framework?
Like spark/hadoop could use mesos/yarn to share resource.

Hi Team,

Hi, everyone!
I'm using fastboot from lxc to flash image to device.
I have link to archive of my image.
How better operate with it?
In lxc test download archive, unzip it to lxc, and flash it ?
I've tried this option. And use lxc:/// url type. But I cant find it, can you suggest how to do it?
my job description : https://pastebin.com/LUmL6Qv3
and I see my downloads in lxc file system. I just removed other commands from job.
I understand,that it is wrong.
I found in glossary
http://59.144.98.45/static/docs/v2/glossary.html#term-lava-lxc-home
But I cant connect path from lxc-container, and lxc:///
Please, help.

Hi Team,
i tried to add Device & Jobs to the LAVA instance for the device type
"qemu" , continuously getting the Configuration Error:missing or invalid
template(jobs requesting this device type (qemu) will not be able to start
until a template is available on the master).
Can you please let me know how to add Device Dictionary to the LAVA
instance.
Thanks in advance.
Regards,
Dhanunjaya. P
