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)?
