Ah, now we're getting somewhere. So you're saying that these devices are
broken anyway, and Kemari happens to trigger that brokenness more frequently?
If the requirement is that a device must support live migration, then that
should be the criteria for enabling Kemari, not some arbitrary whitelist.
If devices incorrectly claim support for live migration, then that should also
be fixed, either by removing the broken code or by making it work.
AFAICT your current proposal is just feeding back the results of some fairly
specific QA testing. I'd rather not get into that game. The correct response
in the context of upstream development is to file a bug and/or fix the code.
We already have config files that allow third party packagers to remove
devices they don't want to support.
