Greetings Hannes, Christoph and Co,
So after some additional discussions on and off the linux-scsi list wrt
to KVM + megasas emulation, I got motivated and decided to try it out
for myself using the QEMU code from Gerd's tree at:
http://repo.or.cz/w/qemu/kraxel.git branch: scsi.v9.
As expected
Greetings Hannes, Gerd and co,
So after doing more digging into the work for a SGL capable QEMU SCSI
HBA emulation interface with the megasas driver on Linux/KVM Hosts, I
realized that the SG_IO breakage we originally encountered is due to the
fact that CDBs containing SBC LBA+block_count where

that hw/scsi-generic.c:execute_command_run() using bdev_aio_ioctl()
appears to be broken for XP guests, which causes the first 36-byte

obtain a file descriptor from either qemu_parse_fd() (the normal case)
or from monitor_get_fd() (migration case) into a generically prefixed

This QEMU patch sets VirtIOSCSIConfig-max_target=0 for vhost-scsi operation
to restrict virtio-scsi LLD guest scanning to max_id=0 (a single target ID

This ensures that virtio-scsi LLD only
