a) after you quit qemu can you try qemu-img check on the qcow2 file to see if it's happy?
b) If you repeat your test using a raw image file rather than a qcow2 is it any happier?
c) How repeatable is it? If it's very repeatable it would be great if you could perform a git bisect to find which commit breaks it; we can walk you through it if you've not done it before.
Hi Claus,
Some things to try:
a) after you quit qemu can you try qemu-img check on the qcow2 file to see if it's happy?
b) If you repeat your test using a raw image file rather than a qcow2 is it any happier?
c) How repeatable is it? If it's very repeatable it would be great if you could perform a git bisect to find which commit breaks it; we can walk you through it if you've not done it before.
