The key arguments from my side for inclusion of virtio-scsi are: - Support for SCSI multipathing, which can optionally be done on the host operating system. - We can now use other SCSI(non-block) devices and make them accessible to the guest. For example we were able to virtualize a SCSI FCP tape using virtio-scsi. One of the biggest constraints of virtio-block is that it is limited to block devices, while virtio-scsi presents you with a more generic solution.
So I consider virtio-scsi to be the cleaner approach to do virtualization of SCSI commands. This is supported by the fact that virtio-block has a maintenance problem and has to change its protocol from time to time to support new features introduced by a new version of the SCSI standard.
So please consider including virtio-scsi into the mainline kernel tree. This is good and conceptually clean code, and it has proven to work very well in our internal testing.
