Without kvm or other HW accelerated virtualization many of those ptests will simply fail on timeout, and if not, they'll still be running when the heat death of the universe occurs.

I was not aware if this image is only meant for x86/arm64.
I do build the same images as AB for qemumips and boot them, although
tests are not run yet regularly matter of time. But building them
itself catches many build issues.

if these images do not have value for other machines then perhaps some
message or comment in recipe, will save some debugging time for
someone in future who is trying to boot it on other arches.
