They have different goals, but it makes sense to run kvm-unit-tests
inside avocado.

kvm-unit-tests is a collection of single-purpose guests that test some
parts of KVM (the kernel).  kvm-unit-tests also contain a simple
framework to let you run those guests without hassle.

avocado-vt is a module for avocado testing framework that allows you to
conveniently automate tests about and inside guests.  avocado-vt also
collects tests for guest that run on KVM.

If you would be using avocado anyway, then it's a good idea to run
kvm-unit-tests from it, instead of running them separately.

(I presume that you'll run something, like jenkins, on top of avocado,
 so having just one set of results will be simpler.)

That depends on what you count and what you actually want to test.
Working with KVM guests is testing KVM. :)

Virtualization mostly emulates real hardware, so pretty much any
hardware test suite is worthwhile and other components in your virt
stack (QEMU, libvirt, ...) have a specialized test suites that also
exercise KVM.

AFAIK avocado(-vt) is the latest try at THE testing framework, so using
it should be more convenient than writing your own framework to test a
huge cartesian product of variables that KVM+QEMU+libvirt+... provides.

I guess that developers mostly use the test suite for their project or
custom tests/benchmarks that cover their current work.

Autotest maybe still is the most popular framework, but avocado
obsoletes it.

Btw. the avocado team will be able to provide much better information.
