A question about libvirt and qemu support for "buslogic"

Simply and fast.
On this page I see


Code:
             When <controller type ='scsi'>, there is an optional attribute model model, which can have the following values:         
  • auto
  • buslogic
  • ibmvscsi
  • lsilogic

Buslogic appear a valid and supported controller,but on qemu said is unsupported


Code:
qemu-system-x86_64 -device lsi,help
lsi53c895a.rombar=uint32
lsi53c895a.x-pcie-lnksta-dllla=bool (on/off)
lsi53c895a.multifunction=bool (on/off)
lsi53c895a.romfile=str
lsi53c895a.x-pcie-extcap-init=bool (on/off)
lsi53c895a.command_serr_enable=bool (on/off)
lsi53c895a.addr=int32 (Slot and optional function number, example: 06.0 or 06)



qemu-system-x86_64 -device buslogic,help
qemu-system-x86_64: -device buslogic,help: Device 'buslogic' not found

The buslogic appear on my libvirt file


Code:
grep -ir buslogic /usr/share/libvirt/*
/usr/share/libvirt/schemas/domaincommon.rng:                  <value>buslogic</value>


Why is present if qemu don't support it?Is used by xen or other hypervisor?
