I tend to agree that not prompting the user here provides better user
experience; however I don't feel like this is a major issue.

Regardless of the severity of the problem, the solution you propose --
disabling the prompts for specific device instance IDs -- is IMO way too
unreliable and PnP manager will still want to interact in a number of
common cases:

- if the devices get enumerated differently and Windows assigns
  different instance IDs to them

- if there's more than one device of any kind

- if there are new devices beyond those you handle (e.g. virtio-serial)

I think this would be better addressed if you could disable PnP manager
prompts globally during v2v, and reset it back in a firstboot script
after your installer had been run.
