Jeffrey,

rax-iad uses xen as a base virtualization layer iiuc.  Perhaps kvm on xen is not a technical feature rax-iad supports or perhaps libvirt was modified and now fails with xen?  Whatever the case is, rax-iad has been a semi-constant source of hassle with Kolla’s gate jobs; I think partly because Kolla’s gate scripts need to special-case rax-iad in some way.

Just one of many possibilities.

Happy new year ☺

I checked more than ten error gates, all of them happened in rax-iad.

Jeffrey,

Have you detected any pattern to any specific cloud provider in the logs?

Found this nova bug[0] and another talk in openstack-dev[1].

The question is: why this happens now and then? sometimes the gate is OK. and others not.

Recently, centos 7.3 is release. libvirt is upgrade to 2.0 version.

But in kolla's gate. the nova_libvirt container failed now and then.

What i found is:

1. Simple start nova_libvirt container is OK.
2. When launching a new instance, libvirt is killed without any logs in libvirtd.log file.
3. in system messages log, i found following line.

Dec 29 00:41:24 localhost kernel: libvirtd[24340]: segfault at 8 ip 00007f9fee072823 sp 00007f9fe52dd1c0 error 4 in libvirt.so.0.2000.0[7f9fedf1f000+353000]

No idea why and how this happen. Any idea on this?
