Xen supports on_crash actions coredump-{destroy,restart}. libvirt cannot parse config returned by xend that contains either of these actions xen52 # xm li -l test | grep on_crash (on_crash coredump-restart) xen52 # virsh dumpxml test error: internal error unknown lifecycle type coredump-restart This patch adds a new virDomainLifecycleCrash enum and appends the new options to existing destroy, restart, preserve, and rename-restart options.
