You are not the first person to request some way of getting at the
host's sysinfo from a libvirt API, so the idea of exporting something
makes sense (just not virSysinfoRead in its current form).  Personally,
I like the idea of:

char *virConnectGetSysinfo(virConnectPtr)

which returns just the XML <sysinfo> block for a given host.  Also,
including <sysinfo> in the larger XML of virCopnnectGetCapabilities()
makes sense.
