IMO the only reasonable solution is to disallow interrupt forwarding

Disallowing shared IRQs means disallowing PCI devices in general, so now
you are back to ISA only devices, which it sounds like were the only
things already allowed by vm86 or whatever it was for passing through.


No, it means disallowing pci devices that use shared irqs, and allowing pci devices that use non-shared irqs.

Certainly does appear to have potential though for allowing more
interesting virtual machines.

IMO pass-through is counter to most of the benefits of virtualization. But users seem to want it.
