## Reproducible

Last good: [20180116](https://openqa.opensuse.org/tests/583951) (or more
recent)

## Manual debug

I reproduced this locally on an openQA instance and at the point seen in the
screenshots, y2start had been killed due to oom.

The openQA workers by default get 1GB RAM allocated, which seems no longer
sufficient with the NET installer; The installation from DVD works with 1GB
RAM.

(as a workaround, we will change the setupt to use 1.5GB for the NET Medium -
so even though openQA will show the tests successful in the future, this is not
magically disappearing)
