Hi I am trying to implement VirtIO support for a proprietary OS. And It would be great if I am able to process SCSI commands over VirtIO Block device. I tried to execute INQUIRY command but the status returned is UNSUPPORTED. If anyone provide example VirtIO SCSI Command request structure for INQUIRY command as per VirtIO spec Appendix D would be a great help. And also, the paragraph from VirtIO spec - 0.8.9 is confusing for me : "Historically, devices assumed that the fields type, ioprio and sector reside in a single, separate read-only buffer; the fields errors, data_len, sense_len and residual reside in a single, separate write-only buffer; the sense eld in a separate write-only buffer of size 96 bytes, by itself; the fields errors, data_len, sense_len and residual in a single write-only buffer; and the status field is a separate readonly buffer of size 1 byte, by itself." Here 'status field of buffer size 1 byte' is whether readonly or writeonly? I want to know from which version of Qemu-kvm supports processing of scsi commands over VirtIO block device as a backend. Although I checked the Host Feature fields in which VIRTIO_BLK_F_SCSI bit is set. I am using qemu-kvm version 0.12.3. -- Anuj Aggarwal Â.''`. : :â :ÂÂ # apt-get install hakuna-matata `. `'` ÂÂ `- _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
