Unfortunately it's not that easy :). The cpumap is unsigned char type
which means it's 8-bit long and each bit represents single CPU.
First we need to get number of host CPUs calling:
ncpus = virNodeGetCPUMap(connect->connection, NULL, NULL, 0);
And then loop over all CPUs and check whether it's set or not using
VIR_CPU_USED macro.
