Unable to create tunnel termination for virtual machine

[abhi1693]

Deployment Type

Self-hosted

NetBox Version

v3.7.1

Python Version

3.10

Steps to Reproduce

1. Create tunel without any terminations at first
2. In the tunnel creation form, choose the newly selected tunnel with type virtual machine and any of its interface

Expected Behavior

A termination for the virtual machine should be created

Observed Behavior

Error of the form is raised

Select a valid choice. That choice is not one of the available choices.

I have debugged this a bit further, the clean method sets the termination which is always picking the Device interface no matter the selection made for the VM. Furthermore, there is an issue with the selector which always remains set for device.

So clearly, any selection made for the VM does show up in the UI but is not taken forward in any requests.

The selector issue can be fixed by adding the following in the init method

self.fields['parent'].widget.attrs['selector'] = 'virtualization.virtualmachine'

But I'm still unsure where the primary issue is coming from.

Another issue I have found is that the edit does not show the selected vm related options in the drop-down
