^ Yes you are right. I wanted to show how use and configure parameter
in control file. This shouldn't be a test this test should be only a sample
of technology. But I made wrong implanting to tests_base.conf. I try think
about tests_base.conf and make this implantation in better way.
I repair subtest and send patch again.

^ This should be standard test in client/tests/
not file from client/tests/kvm/autotest_control.

And yes I agree with this. This sounds good.
