Can you elaborate on this "doorbell" aspect? If you signal interrupts
to guests, they should be signalled as actual interrupts, not as some
hypervisor-specific events, as we rely on the interrupt semantics for
most things.

Or are you talking about injecting an interrupt from a guest into
another, the doorbell representing an interrupt source?

Thanks,
