What were you trying to do that didn't work?

I'm on a RHEL 9.3 system with the following package versions:

virt-install-4.1.0-4.el9.noarch
cockpit-machines-298-2.el9_3.noarch

I am using Cockpit to create a VM with UEFI, and the newly created VM does not automatically have a virtual TPM device added.  Based on the release notes here, I would expect the virtual TPM device would be added for any new VM using UEFI:  https://github.com/virt-manager/virt-manager/releases/tag/v4.0.0

How reproducible:

Every time

Steps to reproduce

1. Use RHEL 9.3 system
2. Create a new VM using cockpit-machines (in my example, I created a Fedora VM, with Operating system set to "Fedora Linux 38")
3. On the new VM page, click "Create and edit"
4. Change the firmware to use UEFI, and then click "Install"

Expected results

Based on the release notes here, I would expect the virtual TPM device would be added for any new VM using UEFI:  https://github.com/virt-manager/virt-manager/releases/tag/v4.0.0

Actual results

No virtual TPM device is added to the new VM:

1. virsh dumpxml <vm_name> | grep -i tpm

(no output)
