Jason, did you have a good solution in mind?


Nope, I'm not familiar with SCSI so I don't even know sharing evt/cvq is possible. Consider VHOST_SCSI_MAX_VQ is already 128 per device. Mike's proposal seems to be better.

Thanks


Btw, it looks to me vhost_scsi_do_evt_work() has the assumption of iovec layout which needs to be fixed.

Thanks
