I think we may want to unrealize more here:

+static void ipmi_sim_unrealize(DeviceState *dev, Error **errp)
+{
+    IPMIBmcSim *ibs = IPMI_BMC_SIMULATOR(dev);
+    IPMIRcvBufEntry *msg, *tmp;
+
+    vmstate_unregister(NULL, &vmstate_ipmi_sim, ibs);
+    timer_del(ibs->timer);
+    timer_free(ibs->timer);
+    QTAILQ_FOREACH_SAFE(msg, &ibs->rcvbufs, entry, tmp) {
+        QTAILQ_REMOVE(&ibs->rcvbufs, msg, entry);
+        g_free(msg);
+    }
+    qemu_mutex_destroy(&ibs->lock);
