> Yes, virtio-scsi is also something we were thinking of. The last time we discussed this idea of SCSI passthrough internally, we stumbled over error recovery. Who is responsible for the error recovery? The host, the guest, or both? Are there problems, which will trigger error recovery in the guest and host midlayer at the same time? To be honest, my scsi knowledge is very limited, so I dont know if that is a real problem.
I'm not that far with planning yet. The best way would be to do real
error handling in the host probably.
