A question about libvirt and qemu support for "buslogic"

Simply and fast.
On this page I see

             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

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

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?

I would say it doesnt cost much to add extra libs they are mostly there to be be used when requested at compilation time and usually you have all possible... so it doesnt mean it can be used.

to me is clear enough, can does not mean supported in your case the option is more likely lsilogic but auto might work
