Whenever client is able to receive some data from stream daemonStreamHandleRead is called. But now the behaviour of this function needs to be changed a bit. Previously it just read data from underlying file (of chardev or whatever) and sent those through the stream to client. This model will not work any longer because it does not differentiate whether underlying file is in data or hole section. Therefore, at the beginning of this function add code that checks this situation and acts accordingly. So after the this, when wanting to send some data we always check whether we are not in a hole and if so, skip it an inform client about its size.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
