I don't have virtualisation extensions on my cpu.  last time i tried
qemu it was much buggier then vbox ;)

please tell the responsible package maintainers.

It is very easy to break an image, be it a change (~git commit) in the
releng env, in archiso or in aif.  I think this is fine (it allows me
to develop quickly), but this also means there can be big differences
in quality between builds. I only want selected high-quality releases
as default download option for the large audience, because
$random_build might be buggy or not even boot.
there needs to be a way to separate crappy builds from good ones.
call it staging vs production, or testing vs main, or autobuilds vs
releases, but there needs to be a way to separate them.  this approach
would allow that in a non-intrusive and relatively elegant way, I think.
It's basically the same as we did before (send mails where you say
"please test these builds and check item foo and bar" and people reply),
but improved because
1)you can see the current state of things more clearly
2)if feature X worked 2 builds ago, and only unrelated things have
changed, that's still valid as a "signoff".

Last time I spoke with Aaron, he also said there should be a way to
promote images when they deserve it, and offer those as official images.
