4. Create an interface on DevB (IntB1)
5. Edit IntB1, set IntA1 as parent

Fix is likely changing self.parent.virtual_chassis to self.device.virtual_chassis.

Thanks for the report, @elipsion ! Is this something you'd be interested in contributing a fix for?

Also, one note for future readers of this issue, it took me a moment to realize that Step 5 of the STR implies that IntB1 is of type Virtual.

Thank you for the STR and pointer, and thanks for the note about Step 5 implying a Virtual interface.

If you don't have time to open a PR, I'm happy to take this on and submit one.
Could you please assign this issue to me?
