Few notes to add to the craziness:

1) According to the qemu documentation the old 'ivshmem' device is
deprecated and should not be used and should be sensibly replaced with
the new devices relevant to the configuration. This is not happening in
this series so the above mentioned bugzilla is actually not resolved by
this series.

2) If we are going to allow migration for the few certain configs that
should work you'll need to add migration flags to support this. The need
comes from the fact that previously we did not parse the model and thus
you will either need to convert previously working configs to the old
device or just to forbid the new definitions.

3) Adding support for the 'role' stuff for the legacy code will add more
fun into making point 2 properly.
