Hi Senthil,

thanks for your reply.

...

I want to set up a multinode job containing an LXC device. Unfortunately I always get the following error:

Missing protocol 'lava-lxc' in ['lava-multinode']

This is because each role should have a lava-lxc protocol defined.

Even real hardware devices?

Going through your job, I could see you are requesting a single device (role) in your multinode job, which is not the use-case which multinode caters. There should be more than one device (roles) requested as part of the job. For a single device, single node jobs are the way to go.

I know, this was deliberate in order to strip the error down to a minimal example. I started out with one LXC device and one real hardware device (which is actually the setup I want to use), which led to the above error. Then I removed parts of the job for simplification until (I hoped) the error would disappear. But it did not, even with a single LXC device. I assume a multimode job should work even if it only contains one single device, shouldn't it?

See https://staging.validation.linaro.org/scheduler/job/213532 - which is a sample multinode job run with two lxc devices requested as part of the job. You can see how each role has a lava-lxc protocol defined for it.

The job definition is available here - https://git.linaro.org/lava-team/refactoring.git/plain/lxc-multinode.yaml

Thanks, that pointed me the way. I had to add an additional "remote" key under "protocols/lava-lxc", so the job looks like this:

job_name: lxc-pipeline timeouts: job: minutes: 15 action: minutes: 5 priority: medium visibility: public

protocols: lava-multinode: roles: remote: device_type: lxc count: 1 timeout: minutes: 6 lava-lxc: remote: name: pipeline-lxc-test template: debian distribution: debian release: stretch mirror: http://ftp.us.debian.org/debian/ security_mirror: http://mirror.csclub.uwaterloo.ca/debian-security/

actions: - deploy: timeout: minutes: 5 to: lxc os: debian role: - remote

- boot: prompts: - 'root@(.*):/#' timeout: minutes: 5 method: lxc role: - remote

- test: timeout: minutes: 5 definitions: - repository: git://git.linaro.org/qa/test-definitions.git from: git path: common/dmidecode.yaml name: dmidecode role: - remote

This job runs without errors, even though it has only one single device in a multinode context. From here I can build my actual multinode job by adding my real device to it.

HTH. Thank You.
