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 :-)
