Currently we use iohelper for virFDStream implementation. This is because UNIX I/O can lie sometimes: even though a FD for a file/block device is set as unblocking, actual read()/write() can block. To avoid this, a pipe is created and one end is kept for read/write while the other is handed over to iohelper to write/read the data for us. Thus it's iohelper which gets blocked and not our event loop. This approach has two problems: 1) we are spawning a new process. 2) any exchange of information between daemon and iohelper can be done only through the pipe. Therefore, iohelper is replaced with an implementation in thread which is created just for the stream lifetime. The data are still transferred through pipe (for now), but both problems described above are solved.

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.
