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.

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.
