In principle they don't have to be the same across hosts since you can
identify the network by name and the volumes by their path but I prefer
to keep them in sync (using shared nfs in my case).

Yes sure. I share configs across hosts and reload libvirtd's
configuration when adding new kvm vms so it picks up the new
configuration.
