At least with systemd v210, NOTIFY_SOCKET is abstact, e.g.
@/org/freedesktop/systemd1/notify. sendmsg() fails on such a socket
with "Connection refused". The unix(7) man page contains the following
details wrt abstract socket addresses
abstract: an abstract socket address is distinguished (from a
pathname socket) by the fact that sun_path[0] is a null byte
('\0'). The socket's address in this namespace is given by the
additional bytes in sun_path that are covered by the specified
length of the address structure. (Null bytes in the name have
no special significance.)
So we need to be more precise about the address length, setting it to
the sizeof sa_family_t + length of address copied to sun_path instead
of setting it to the sizeof the entire sockaddr_un struct.

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.
