Hi Rolandas<br>
<br>
So the problem is how to update the version of an image, right? We are<br>
currently copying the new file to the SOURCE of the image something like:<br>
<br>
cp debian_new.qcow2 `oneimage show debian | | grep SOURCE | cut -d':' -f2`<br>
<br>
This way you do not need to modify the qcow driver.<br>

As I wrote in <a href="http://mif.vu.lt/~rolnas/stsc/qcow2.txt" target="_blank">http://mif.vu.lt/~rolnas/stsc/<u></u>qcow2.txt</a> we cannot simple replace qcow2 image with cp or mv, because original image could still be in use by some VM (referenced as backed file in snapshot qcow2). Until VM is running it is OK, because original file is still open by kvm, but when VM is stopped or turned off (power off), kvm process is terminated and original file is deleted, but snapshot qcow2 is still referencing original file by pathname.<br>
<br>
Regards<br>

Hi,<br>
<br>
For management of master images in qcow2 format we created a<br></div>
solution described here <a href="http://mif.vu.lt/~rolnas/stsc/__qcow2.txt" target="_blank">http://mif.vu.lt/~rolnas/stsc/<u></u>__qcow2.txt</a><br>
<<a href="http://mif.vu.lt/%7Erolnas/stsc/qcow2.txt" target="_blank">http://mif.vu.lt/%7Erolnas/<u></u>stsc/qcow2.txt</a>>. Hope it could solve<div class="im"><br>
some management troubles and we are looking for improvements in<br>
OpenNebula also.<br>
<br>
