I am looking for a suitable method for the following use-case: during test, I need to access the connection to the workstation that runs my LAVA worker and use it as a second namespace in order to be able to issue some commands on the the workstation (like playing an audio file). In other words I need to integrate the workstation as an auxiliary device needed for testing in the test job definition (like ssh <user>@<ws_ip_addr> and send some commands). Using LXC is not an option at this moment.
At a first sight, the Multinode support would have the most of the needed features, but I did not find an example of such an usage, if there is any example you can point me to, I will be grateful.

Thank you in advance,
Oana Ercus
