You need to install the file in /etc/libvirt/qemu/networks instead.
If you want the network to be autostarted, you also need to create a
symlink in /etc/libvirt/qemu/networks/autostart that points to the
network XML and has a matching name.
Note that if you do this, you'll need to "preprocess" the .xml file by
net-define'ing it on some system so that all the necessary elements are
there, and then using the resulting xml rather than your original - for
example, each network must have a <uuid> element, but that is usually
filled in automatically when the network is net-defined.
Also, if you do this keep in mind that the fact that these files are
currently in /etc/libvirt/qemu/networks is not a part of libvirt's
public API - it could be changed at any time by an update (although this
has never happened). The same is true for all other .xml files in
/etc/libvirt; only the .conf files are public.
