VirtualBox API exports Host-Only adapter without name

[ana06]

When I export an appliance adding a VM with a Host-Only adapter manually (using the GUI), the exported appliance include a name for the HostOnlyInterface and I can import and run the VM correctly:

<HostOnlyInterface name="vboxnet0"/>

But if I use the VirtualBox API to export an appliance adding a VM with a Host-Only adapter, the name of the HostOnlyInterface is missing, causing a "Nonexistent host networking interface, name (VERR_INTERNAL_ERROR)":

<HostOnlyInterface/>

I would expect the VirtualBox API to either export the name of the Host-Only adapter by default or accept a name, for example as part of the extraConfigValues of the IVirtualSystemDescription: 'type=HostOnly;name=vboxnet0'.

I am using the following Python code (using ​virtualbox-python which is a wrapper for VirtualBox's COM API, but the issue is not Python related) to export the VM:

vbox = virtualbox.VirtualBox()
vm = vbox.find_machine(VM_NAME)

appliance = vbox.create_appliance()
sys_description = vm.export_to(appliance, "name")
appliance.write("ovf-1.0", [], PATH)

This code is part of the following script open-sourced as part of the FLARE-VM project: ​https://github.com/mandiant/flare-vm/blob/main/virtualbox/vbox-export-snapshots.py

I have tested this code in Debian with VirtualBox 7.0.20 and different hosts (Windows 10 and Ubuntu). In addition to this bug report, I have opened the ​''Export to OVA with Host-Only adapter with name'' topic in the VirtualBox forum looking for solutions or workarounds to this issue.

Please let me know if there is anything I can do to help fixing the issue.
