结合源码查看
# qemu/qemu_driver.c
if (virDomainObjGetState(vm, NULL) != VIR_DOMAIN_SHUTDOWN) {
VIR_DEBUG("Monitor connection to '%s' closed without SHUTDOWN event; ""assuming the domain crashed", vm->def->name);
stopReason = VIR_DOMAIN_SHUTOFF_CRASHED;
qemuProcessStop(driver, vm, stopReason, VIR_ASYNC_JOB_NONE, stopFlags);
# qemu/qemu_process.c
void qemuProcessStop(virQEMUDriver *driver,
virDomainObj *vm,
virDomainShutoffReason reason,
virDomainAsyncJob asyncJob,
unsigned int flags)
if ((timestamp = virTimeStringNow()) != NULL) {
qemuDomainLogAppendMessage(driver, vm, "%s: shutting down, reason=%s\n",
timestamp,
virDomainShutoffReasonTypeToString(reason));
}

Oct 12 07:42:42 xx kernel: Out of memory: Kill process 6875 (qemu-kvm) score 145 or sacrifice child
确定是因为物理机内存不足导致的问题。
