When using the monolithic daemon the driver for virStream is always virFDStreamDrv and thus calling virStreamInData() results in calling virFDStreamInData(). But things are different with split daemon, especially when a client connects to one of hypervisor daemons (e.g. virtqemud) and then lets the daemon connect to the storage daemon for vol-upload/vol-download. Here, the hypervisor daemon acts like both client and server. This is reflected by stream->driver pointing to remoteStreamDrv, which doesn't have streamInData callback implemented and thus vol-upload/vol-download with sparse flag fails.
