We have problem using qemu emulated scsi driver(the old lsi). Wonder if any of
other device model we can try for emulating scsi, and how we can get and config
it in Xen? Having been told virtio-scsi is alternative one, but have no idea
how to get it work in Xen.
The MegaSAS HBA might be another option. Not sure whether MegaSAS or
virtio-scsi are supported under Xen though.
Making MegaSAS HBA work on Xen should be easy.
Rather than virtio-scsi I would consider the new Xen pvscsi frontend/backend
drivers, now upstream in Linux (drivers/scsi/xen-scsifront.c and
drivers/xen/xen-scsiback.c). Usually Xen PV drivers perform much better than
virtio devices on Xen.
That said, probably most things would be better than the old lsi.
