A cygwin build of the qemu driver fails with: qemu/qemu_process.c: In function 'qemuPrepareCpumap': qemu/qemu_process.c:1803:31: error: 'CPU_SETSIZE' undeclared (first use in this function) CPU_SETSIZE is a Linux extension in <sched.h>; a bit more portable is using sysconf if _SC_NPROCESSORS_CONF is defined (several platforms have it, including Cygwin). Ultimately, I would have preferred to use gnulib's 'nproc' module, but it is currently under an incompatible license. * src/qemu/qemu_conf.h (QEMUD_CPUMASK_LEN): Provide definition on cygwin.

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.
