No - libvirt intentionally allows you to omit address assignment when
first defining the guest, at which point libvirt will then fill in the
information for you, so that future uses of the guest will have an
assigned address.

The easiest way is to omit the guest assignment from your XML, and let
libvirt manage it.  The guest view is completely independent from the
host view, so you don't need to worry about address collisions with the
host.
