Hi Dmitry,<br>
<br>
Could you please have a quick try with the official "Generic" image from<br>
the Debian team? Best maybe would be to try this one:<br>
<br>
<a href="http://cdimage.debian.org/cdimage/cloud/bullseye/daily/20201216-486/debian-11-generic-amd64-daily-20201216-486.qcow2" rel="noreferrer" target="_blank">http://cdimage.debian.org/cdimage/cloud/bullseye/daily/20201216-486/debian-11-generic-amd64-daily-20201216-486.qcow2</a></blockquote><div><br></div><div>Only if DIB provides support for it. I'm not inclined to reproduce the whole generation process manually.</div><div><br></div><div>Dmitry<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>
<br>
Indeed, I would very much like to be able to validate the image works<br>
for Ironic.<br>
<br>
Cheers,<br>
<br>
Thomas Goirand (zigo)<br>
