The functions to retrieve online and present host CPU information are only supported on Linux for the time being. This leads to runtime errors if these function are used on other platforms. To avoid that, code in higher levels using the functions must replicate the conditional compilation in higher level which is error prone (and is plainly spoken ugly). Adding a function virHostCPUHasBitmap that can be used to check for host CPU bitmap support. NB: There are other functions including the host CPU count that are lacking support on all platforms, but they are too essential in order to be bypassed.

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.
