Yes, using KVM and multinode means that you do not use the python
environment on the dispatcher. The python script then runs in a python
environment which you define, inside the KVM. You need to make sure
either that this image has any python dependencies pre-installed or
that the necessary python support is installed before the script runs.

Not unless you have a way of deploying the python interpreter as part
of your test or part of the image.

Your tests in the KVM need to use ADB to run tasks on the DUT.

Just for clarity and for others reading the list, this is a run.sh as
generated by LAVA. Do not use LAVA_SIGNAL in test scripts.
