I hope you understand the concern I have is not with you in particular,
and I used your case to start a discussion with the QEMU community.
Hi Philippe,
Yeah I understand. I agree as well we should try to find a long-term general solution.
FWIW I missed the URL change because I still have the image cached in
Avocado so my testing ran fine. Which makes me wonder...
Cleber, Willian, should Avocado display information about cached
artifacts? Such "Using artifact downloaded 7 months ago".

Until there is better solutions, this is the option I prefer.
Allright, I'll prepare a reworked patch soon that uses github and re-send it.
Kind regards,
Niek
