This patch introduces a new libvirt API (virDomainGetVcpupinInfo), as a counterpart to virDomainPinVcpuFlags. We can use virDomainGetVcpus API to retrieve CPU affinity information, but can't use this API against inactive domains (at least in case of KVM), as it lacks a flags parameter. The usual thing is to add a new virDomainGetVcpusFlags, but that API name is already occupied by the counterpart to virDomainGetMaxVcpus, which has a completely different signature. The virDomainGetVcpupinInfo is the new API to retrieve CPU affinity information of active and inactive domains. While the usual convention is to list an array before its length, this API violates that rule in order to be more like virDomainGetVcpus (where maxinfo was doing double-duty as the length of two different arrays).

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.
