Re: [ovirt-users] Ovirt 4.0 to 4.1 CentOS7.3 and libvirtd 2.0.0 segfault issue

2017-04-21 Thread Rafał Wojciechowski 

hello,

I am not sure.
I have simple openvpn client profile with systemd enabled on boot time, 
but I think I was not included it anywhere for libvirt/ovirt purpose.


also strange for me was statement that this interface was without IP - 
this interface should be up with IP after connection established... but 
anyway even if some dependencies occurs, then it should be handled 
somehow with proper error.


Regards,

Rafal Wojciechowski

Yes, "-1" means "autoallocation from libvirt".
I don't see obvious issues in this XML, and, most
importantly, one
invalid XML should never cause libvirtd to segfault.

I'd file a libvirt bug.

2017-04-21 Thread Rafał Wojciechowski 

hi,

my issue was related to bug in libvirtd.
it was found in core dump by libvirt team

"

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
