In the following cases nl_recv() was returning the error "No buffer space available": * When switching CPUs to offline/online in a system more than 128 cpus * When using virsh to destroy domain in a system with many interfaces This patch sets the buffer size for all netlink sockets created by libnl to 128K and turns on message peeking for nl_recv(). This eliminates the "No buffer space available" errors seen in the cases above, and also preempts other future errors the smaller buffers could have caused.

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.
