Fellow cloudies,
The recent builds of our images are v3 qcow2 (also known as qcow3).
This presents a problem for our testing, since the openstack
instances we have access to don't support v3, only v2. The only
difference between v2 and v3 are some performance enhancements - so
the question is, should we produce v2 images instead of v3 for easier
testing?
This would require us to request a tweak from releng to get the
correct format, but would stop us from having to use a workaround [0]
to test (and I worry about testing a converted image - because then
we rely on "well, it *should* be the same" for our test results).
Thoughts?
[0] qemu-img amend -f qcow2 -o compat=0.10 <image.qcow2>
it would require patching in koji, we require that the tools create the
correct thing and do not do manipulation after.
