I don't think it is right to link to libvirt.la here or with other
driver modules.

The libvirtd daemon links to libvirt.la already, and is built such
that all exported symbols are available to modules that are dlopen()d
Thus it should be sufficient to add symbols to libvirt_private.syms
and not link to libvirt.la in driver modules.

I don't think that works on Windows. Windows DLLs must not have undefined symbols. They do not get "magic" access to symbols exported by previously loaded libraries and (as in this case) programs.
