I'm afraid I don't understand your question. Which hypervisor are you 
using that you think virConnectNumOfNetworks isn't supported. The only 
possible meaning I can get from the above sentences is that you think 
virConnectNumOfNetworks isn't supported when qemu is the hypervisor, 
which is definitely *not* true.

As a matter of fact, essentiall *all* of the functions in the matrix are 
supported when qemu is the hypervisor, pretty much every one of them 
ever since their original introduction (e.g., the function you reference 
has been supported since libvirt 0.2.0, which was released in February 
2007).

Are you possibly misinterpreting the contents of the support matrix?
