As of ff024b60cc3 we are opening chardevs before starting QEMU. However, we also doing that before domain private directories are created. This leaves us impossible to create guest agent socket which lives under priv->channelTargetDir. While creating the dirs can be moved just before qemuProcessPrepareHostBackendChardev() it's better to do it as the very first step so that this kind of error is prevented in future.
