<div>Dear all</div>
<div><br>
</div>
<div>I am not sure if the mail just did not get any attention between all the mails and this time it is also going to the libvirt mailing list.</div>
<div><br>
</div>
<div>I am experiencing a problem with VM becoming unresponsive when removing Snapshots (Live Merge) and i think there is a serious problem.</div>
<div><br>
</div>
<div>Here are the previous mails,</div>
<div><br>
</div>
<div><a href="http://lists.ovirt.org/pipermail/users/2015-May/033083.html">http://lists.ovirt.org/pipermail/users/2015-May/033083.html</a></div>
<div><br>
</div>
<div>The problem is on a system with everything on the latest version, CentOS 7.1 and ovirt 3.5.2.1 all upgrades applied.</div>
<div><br>
</div>
<div>This Problem did NOT exist before upgrading to CentOS 7.1 with an environment running ovirt 3.5.0 and 3.5.1 and Fedora 20 with the libvirt-preview repo activated.</div>
<div><br>
</div>
<div>I think this is a bug in libvirt, not ovirt itself, but i am not sure. The actual file throwing the exception is in VDSM (/usr/share/vdsm/virt/vm.py, line 697).</div>
<div><br>
</div>
<div>We are very willing to help, test and supply log files in anyway we can. </div>
<div><br>
</div>
<div>Regards</div>
