Can you define (in plain English) what is the "correct" address?
The host may have multiple valid addresses (storage, migration, display,
whatnot).

Only when it's clear to us, we can start expressing this in Python.

It might be a valid hack to drop this default virbr0 on vdsm start - not
only the libvirt definition thereof, but also the running kernel device.

However, as expressed above, this would not solve your problem when you
have a currently-running host with multiple addresses.
