John, Craig,

When I initially proposed the idea:


it was meant to be mainly a regression testing tool for FreeBSD.  Something
that would let me build and run continuous builds for FreeBSD ARM (ZEDBOARD
kernel), and then make a SD image out of it, which I can boot in QEMU/real

It would be nice if we payed attention to BHyVE in this project, but not
limit ourselves to it. E.g.: ARM testing was my original drive towards
proposing this.

For such a system I'd like to be able to recognize what is being printed on
UART at the boot time. Then register the output in a file and later compare
it. And I'd like enough expressiveness to say: "if there's no login screen
after 30s of bot time, fail and let me know what the screen content at the
time of failure was".

DSL isn't a must here, I agree, but you'll be limited in testing otherwise.
Unless some technology already has what I want, I suggested getting this

        vm0 = vm.start("vm0");
        vm1 = vm.start("vm1");



        vm0.cmd("ifconfig .....");
        vm1.cmd("ifconfig ....");

        vm0.cmd("ping vm1");

        vm0.register(function(data) {
                if (data =~ /*Not*/) {

Once this would work for VMs, I'd be interesting in proposing the creation
of the physical infrastructure for continuous FreeBSD testing. We could
start this from Atom-based PC and Raspberry PI netbooting latest FreeBSD.

If John sees it in a similar way and he'd like to explore this path, I'd be
very interested in mentoring this idea. But once again: only if there isn't
something of a similar functionality.
