libvirt users - Apr 2017 - libvirtd segfault when using oVirt 4.1 with graphic console - CentOS7.3

hello,

I am getting such error:
libvirtd[27218]: segfault at 0 ip 00007f4940725721 sp 00007f4930711740 
error 4 in libvirt.so.0.2000.0[7f4940678000+353000]

when I am trying to start VM with graphic spice/vnc console - in 
headless mode(without graphic console) it is running
I noticed this after update oVirt 4.0 to oVirt 4.1 however I noticed 
that also libvirtd and related packages were upgraded from 1.2.7 to 2.0.0:
libvirt-daemon-kvm-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-qemu-2.0.0-10.el7_3.5.x86_64

I am running up to date CentOS7.3 with 3.10.0-514.16.1.el7.x86_64
I have same issue with SELinux and without SELinux(checked after reboot 
with permissive mode)


I tried to get information about this issue from oVirt team, but after 
mail conversation both me and oVirt team thinks that it might be issue 
in libvirtd

in below link I am putting xmls generated by vdsm which are passing to 
the libvirtd to run the VMs
first one is from vdsm log and second one is extracted from dump after 
segfault of libvirtd

Hi,

could you please provide core backtrace? I've tried to reproduce it on
CentOS 7.3 with the same graphics configuration but the guest started
and there was no segfault.

Thanks,

Pavel

hello,

I attached core dump - not sure if it was what you have asked for
I am rather just admin not developer :)
