Judging by how the whitelist has skewed quite far from the original
error message, I think it's better to just drop these.

If someone wants to revive this check I suggest implementing it on
a per-HV driver basis with PostParse callbacks.

Definitely the error messages for the current checks are incorrect, and certain types that are allowed here would actually be invalid for some hypervisors/machinetypes (the example you gave me in IRC was that vmware doesn't have virtio-mmio, nor do most qemu machinetypes), so you are correct that the proper place for at least some of the validation is in a post-parse callback.

There is some value in the current validation, but it's dubious since any failure would have led to a misleading error message. Based on that I say ACK to this, but someone should put "improve address type validation in postparse" on their todo list :-)
