Many thanks for your answer and for passing it along.

I agree, an option to trigger this behavior is best.

After executing the above command and before the hostname step, the
following workaround seems to work:

$ virsh net-dhcp-leases default
 Expiry Time           MAC address         Protocol   IP address
  Hostname   Client ID or DUID
-----------------------------------------------------------------------------------------------------------------------------------------------
 2020-03-27 18:03:36   52:54:00:9d:d1:e7   ipv4       192.168.122.45/24
  -      ff:00:9d:d1:e7:00:01:00:01:26:10:e0:58:52:54:00:9d:d1:e7

$ virsh net-update default add ip-dhcp-host "<host
mac='52:54:00:9d:d1:e7' name='try06' ip='192.168.122.45'/>"


What I am not sure about is how to predetermine the MAC address of the
guest before starting the installer?


Is there a predictable/better  way to go about this?


Again thanks for opening a ticket on my behalf and for your answer, much
appriciated.
