What is the disadvantage of dispatching the MSI interrupts to the vcpus
via the IOAPIC? Pin shortage I can think of, but adding more IOAPIC's is
possible (and wanted anyway for systems with insane amounts of net/block
devices).

That would avoid code duplication (might need to handle a few msi
specific bits).
