From: Nicholas Bellinger <nab at linux-iscsi.org> This patch changes virtio-scsi to use a new virtio_driver->scan() callback so that scsi_scan_host() can be properly invoked once virtio_dev_probe() has set add_status(dev, VIRTIO_CONFIG_S_DRIVER_OK) to signal active virtio-ring operation, instead of from within virtscsi_probe(). This fixes a bug where SCSI LUN scanning for both virtio-scsi-raw and virtio-scsi/tcm_vhost setups was happening bef...

I have a sles10sp3 vm that I''m trying to passthrough a scsi card, which has a DLT tape drive attached. Anyone doing anything similar? When I passthrough the scsi card (forced to do both ports), the vm dies when it loads, I think during udev. I''m viewing the vm through virt-manager, so I can''t scroll up and see what everything says. Is there a way to get the text xm

Rusty, please review this, and consider for this merge window. This fixes the following virtio spec compliance issues: 1. on restore, drivers use device before setting ACKNOWLEDGE and DRIVER bits 2. on probe, drivers aren't prepared to handle config interrupts arriving before probe returns 3. on probe, drivers use device before DRIVER_OK it set Note that 1 is a clear violation of virtio
