Hi Neil Thanks for sharing detailed information to work with LXC.

1. I am following sample pipeline job with BBB.

https://git.linaro.org/lava/lava-dispatcher.git/tree/lava_dispatcher/pipelin...

I have modified this job details with following value, but i am getting an Error as ['Invalid job - missing protocol']

Check with the valid job: https://staging.validation.linaro.org/scheduler/job/178130

As i have defined protocol as "lava-lxc" which is valid protocol, But job object does not have any protocol details, i have verified by printing details of self.job.protocols is []

Then that is an invalid job. Your modifications have got something wrong. There are a lot of changes in your file against the example. Change only one thing at a time.

2. How test action execute on lxc and device ?

Run a test action in the same namespace as the LXC. In the case of the example, namespace: probe.

https://staging.validation.linaro.org/scheduler/job/178130/definition#deflin...

Can we execute test action in this process
First lxc test action execute --->  Device1 test action execution start

-> Device2 test action execution start

================================================== device_type: beaglebone-black

job_name: LXC and bbb

Please attach files to emails to the list. There's no need to quote the entire file to the list.

Take time to understand namespaces. The LXC is transparent and the namespaces are used to tie the different actions together into one sequence in the LXC and one sequence for the test device.

LXC protocol support is not the same as MultiNode - operations happen in series. The LXC protocol is not a substitute for MultiNode either. If you need parallel execution, you have to use MultiNode.

Split up your test shell definitions if necessary.

Also, attach (not include) the full test job log because that contains details of the package versions being used and other information.

Hi Everyone Hopefully everyone is doing well in this group. Main intend of writing this email to seek assistance in regard to one feature of Lava as lava-lxc which help to create a LXC instance on worker

https://staging.validation.linaro.org/scheduler/job/174215/definition#deflin...

...

and then we can execute any script on worker and propagate its characteristics and result in another actions of Job on board.

That isn't entirely clear. What are you trying to do in the LXC?

You need to deploy an LXC, start it with a boot action for the LXC and then start a test shell in the LXC where you can install the tools you need to execute.

Talking to the device from the LXC can be difficult depending on how the device is configured. To use networking, you would have to have a fixed IP for the device. To use USB, you need to use the device_info support in the device dictionary to add the USB device to the LXC.

...

 I have gone through documentation shared on Lava V2 instance for

LXC job creation, but i am not able to successfully execute job on Debian Jessie Release.

https://validation.linaro.org/static/docs/v2/deploy-lxc.html#index-0

Can you assist me and share a reference process/document to proceed further to create a job using this feature.

More information is needed on exactly what you are trying to do, how the LXC is to connect to the device and what support the device offers to allow for those operations.
