Thanks. I thought this made sense, but I didn’t understand the docs. I found a blog post that showed some of it, though I still don't fully understand all the options.
virsh net-update default add-last ip-dhcp-host '<host name="rhel7-master" mac="52:54:00:5c:1d:d7" ip="192.168.122.2"/>' --live --config
virsh net-update default delete ip-dhcp-host '<host ip="192.168.122.2"/>' --live --config
These seem to do what I want.

It isn't well documented, but the 'virsh net-update' command is what you wnat. It allows you add/remove DHCP host mappings on the fly
