Can you elaborate and add more information on which tests fail without
these configs. I am all for adding configs, however I would like to
see more information explaining which tests don't pass without this
change.

The KVM tests are skipped without these configs:

        dev_fd = open(KVM_DEV_PATH, O_RDONLY);
        if (dev_fd < 0)
                exit(KSFT_SKIP);
