Hi Lava users,


I am using the sample you sent me last week to run tradefed: https://gist.github.com/mwasilew/e6e80a351d43388b1c3342098012ec


Until we have a real device to run on Tradefed we decided to use it with qemu, so the question is:


  1. How do we deploy android on qemu via Lava?
  2. How to boot android via lava?


Do you have any sample job for the above questions?

Here is the answer I have just received from Linaro via their mail-list.

They say it is not a good idea to build tradefed with lava, but it can be used in the scenario to run TF from an LXC container - they have said.
Tradefed should be built from outside Lava.

yes, exactly. Here is an example job definition:
https://gist.github.com/mwasilew/e6e80a351d43388b1c3342098012ec5c

I can't share the actual job and logs as there are passwords included.

Secondly IIUC you need to have dependency between build and run steps. If you want to implement this using LAVA this implies multi-node job. There is no other way LAVA will manage dependencies and timings between executions. So this is getting pretty complicated already.

One is using single node job with LXC container acting as a host side. Other is using multinode and can shard tests between multiple devices. However tradefed packages are built outside of lava and downloaded before job starts.
