The problem with running after the PnP is that user will be prompted for installation of virtio-net and virtio-balloon drivers... which doesn't make sense as we are going to install them automatically anyway.

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)
Hum, I fear you're right.
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.
Any idea how to do that? -- Cedric
