+Subject: [PATCH] qemu: pre-create the dbus directory in qemuStateInitialize
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There are races condiction to make '/run/libvirt/qemu/dbus' directory in
+virDirCreateNoFork() while concurrent start VMs, and get "failed to create
+directory '/run/libvirt/qemu/dbus': File exists" error message. pre-create the
+dbus directory in qemuStateInitialize.
