I think optimally we should check if we are running in rax-iad, and if so, set libvirt virtualization to qemu. I was pretty sure the gate script that sets up the system sets the libvirt type to qemu. After inspection of the gate scripts, this is not the case. Perhaps it was setup this way previously and someone changed it.
This explains why rax gates have been so flakey for a very long time when running the deploy jobs.

We need to change nova config to pure qemu without kvm. I thought we did that in gates?

I don't have any answers but my first thought was maybe it is related to https://bugs.launchpad.net/nova/+bug/1643911; however, that affects libvirt 1.3.1 on Ubuntu Xenial and there is at least one instance of that occurring on a non Xen hypervisor so maybe they are not related. Also noticed that you appear to have two redundant sets of system logs in the Kolla centos job(s). See http://logs.openstack.org/80/415880/1/check/gate-kolla-dsvm-deploy-centos-binary-centos-7-nv/d94c349/logs/system_log/ and http://logs.openstack.org/80/415880/1/check/gate-kolla-dsvm-deploy-centos-binary-centos-7-nv/d94c349/logs/system_logs/. As for debugging this you may be able to install libvirt's debugging symbols (http://debuginfo.centos.org/7/x86_64/libvirt-debuginfo-2.0.0-10.el7.x86_64.rpm), capture a core dump, load into gdb and go from there.
