Plus there is no guarantee that we even see events when a hot-add occurs. So any thingie we put in here has a really high chance of breaking other installations. I wouldn't even bother to attempt this; it's virtualized anyway so you can as well switch to the SAS emulation here. Or use a different SCSI parallel emulation like the Symbios/LSI 53c800 one.
