Hi,
At present, vhost-scsi device do not boot in Qemu, but some clients/users have
requirements for that in some scenarios. Of course if we want complete the
aim we should make some changes both Qemu and kernel (vhost-scsi driver
module, it need to add an IOCTL interface to get target_id/lun_id etc.).
Can we do it for Qemu side first? Have any difficulty?
Thanks for any comments.
BTW, I had some patches for this, and tested well.
And I want to post them if possible. :)
Best regards,
-Gonglei

Qemu haven't provide a bootindex property for vhost-scsi device.
So, we can not assign the boot order for it at present.
Sorry for misunderstanding. :(
