<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Gianluca,
<div><br>
</div>
<div>it took me some time to correct my misunderstanding. I advised to update</div>
<div>only libvirt as I was aware of the (old) block-commit command of qemu. </div>
<div>With that you can merge snapshots in the chain (history) but not into the </div>
<div>active <span style="font-size: 10pt;">layer (the current </span><span style="font-size: 10pt;">running state). Merging data into the active</span></div>
<div><span style="font-size: 10pt;">layer needs active-commit that is available since qemu 2.0 . That explains </span></div>
<div><span style="font-size: 10pt;">the </span><span style="font-size: 10pt;">error you got.</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">OVirt makes use of the second scenario so no luck without a full installation</span></div>
<div><span style="font-size: 10pt;">of virt-preview repos or a jump towards FC21.</span></div>

<p dir="ltr">Wow. Very quick test. Thanks for sharing the results. I will have a look what qemu 1.6.2 might need.</p>
<p dir="ltr">Regarding stability of qemu 2.1.2: You should scan the qemu stable mailing list if some severe fixes have been posted after the release. If you feel comfortable take qemu from the preview repos too.</p>
<p dir="ltr">Just a simple yum update.</p>
<p dir="ltr">Remark: With the advent of FC21 virt-preview for FC20 might see no further fixes.</p>

<div>OK, I reply to myself<br>
</div>
<div>The error above is explanatory...<br>
</div>
<div>I didn't notice that only the libvirt part is included in the ovirt-3.5-fedora-virt-preview repo:<br>
</div>
<div><br>
"<br>
[ovirt-3.5-fedora-virt-preview]<br>

</div>
<div>SO I think I need qemu-2.1.2-6.fc20.x86_64.rpm and probably other packages as provided by virt-preview.<br>
</div>
<div>What could be the safest way to include further qemu packages?<br>
</div>
<div>How stable is qemu 2.1.2 at this time?<br>
<br>
</div>
<div>Thanks,<br>
Gianluca<br>
