<p>hi,</p>
<p>my issue was related to bug in libvirtd.<br>
it was found in core dump by libvirt team</p>
<p>"</p>
<pre>I'll send a patch to upstream libvirt to fix this crash. However it can take
a while to get it back to CentOS/RHEL. The source of this crash is that you
have a "tun0" network interface without IP address and that interface is
checked before "ovirtmgmt" and it causes the crash. You can workaround it
by removing the "tun0" interface if it doesn't have any IP address.

<div>Hi Rafal<br>
</div>
not sure it relates to your issue, but i experienced a
similar issue with segfault (running on fedora 25)<br>
</div>
to resolve it i had to remove glibc packages and then
install them again (maybe a same workaround for libvirt
will do the job here)<br>
<br>

<br>
</span>Yes, "-1" means "autoallocation from libvirt".<br>
I don't see obvious issues in this XML, and, most
importantly, one<br>
invalid XML should never cause libvirtd to segfault.<br>
<br>
I'd file a libvirt bug.<br>
