Hi Michael, I just have some comments on what you changed on
stress_boot. :-)

Actually, there are two methods to deal with started VMs via framework, one is
as soon
as the current test finished and the other is just before next test going to be
started.
In this case both methods equal somewhat between each other I think, and
I had chosen the later one. But if you had done some testing and
proved the previous one is better, I would agree.

This has been specified within code during cloning.

If you add this option '-snapshot' here, the first VM will be in snapshot
mode as well which will affect next test.
