Although virtio-scsi supports SCSI PR, the device on host may do not support it. To avoid losing data, we only allow one scsi hostdev to be passthroughed to one live guest, Just like what we do for PCI and USB devices.

--- v2.5 - v3: * Small changes, mainly on errors & coding style I think this restriction should be limited to devices that do not have a <shareable/> element, similar to disks. I created BZ957292 for this. Right, I should use PATCH 0/n in the cover letter to indicate there are still patches left.. They are in hand, but not good tested. Will send them later & took the bug.
By the way, is there other -drive property which is nice to have for scsi-generic? Except the readonly.. (discard, serial, werror/rerror, and cache, I don't see other useful properties for scsi-generic)?
discard/serial/cache are not supported. rerror and werror are but they will be. Paolo
