.... If you are still able to reproduce the crash, can you try to get the line number within virSecurityManagerGenLabel where the crash happened? I think it's the STREQ line (440 linenr). Question is whether model or name is NULL. src/security/security_manager.c-438- for (i = 0; i < vm->nseclabels; i++) { src/security/security_manager.c-439- for (j = 0; sec_managers[j]; j++) src/security/security_manager.c-440- if (STREQ(vm->seclabels[i]->model, sec_managers[j]->drv->name)) src/security/security_manager.c-441- break; src/security/security_manager...

...have what you need: Line #442. However, the line numbers for the source code in the source tree that my Gentoo system is building from does not match exactly what you listed. Line #442 for me is the one containing the "STREQ" macro: virObjectLock(mgr); for (i = 0; i < vm->nseclabels; i++) { for (j = 0; sec_managers[j]; j++) if (STREQ(vm->seclabels[i]->model, sec_managers[j]->drv->name)) break; I can rebuild with "-O0" and try again. If I can still trigger the crash, the backtrace might have useful values for the opt...

Update: I am able to edit the XML in "dwj-hfax-dev" such that libvirtd no longer crashes, and edit the XML for "dwj-lnx-dev" such that it will crash. The presents of "<seclabel type='none'/>" near the bottom causes libvirtd to crash. I do not recall ever manually adding that to my domain. In any event, libvirtd should probably not crash due to the
