I'm afraid the emulated LSI SCSI adapter has known issues and doesn't
seem to be under active development.

Use IDE for compatibility or virtio-blk if you're willing to install the
virtio-win guest drivers.  There is also SATA (AHCI) and MegaSAS SCSI
support if you don't want to use IDE/virtio-blk.
