How to tell Foreman to create libvirt domains (VMs) with short hostname?

Using Foreman 3.7, I want new libvirt VMs to be created with the short hostname used for the VM name (a.k.a. the “domain name” in libvirt terminology). So for newserver55.example.com, I want virsh list to show “newserver55” not “newserver55.example.com”.

This is how it worked in the ancient Foreman version I am migrating away from (1.22.0-develop).

Where is this behavior controlled? How can I make Foreman 3.7 use the short hostname for libvirt VMs?

I found it, it’s in the UI under Administer → Settings → Provisioning.
