There are two possibilities:

1) If the network is already active when you edit it, you won't see the
change in the output off virsh net-dumpxml until the next time you
restart that network. (alternately, you can see it immediately with
"virsh net-dumpxml --inactive", but that will also show any other
changes you've made to the network config that won't take effect until
the next restart of the network).

2) Your libvirt version is older than 2.1.0 (when <metadata> was
introduced to the network XML). You can see the version of your libvirt
with "virsh -v".
