[Qemu-devel] [PATCH 0/6] More sensible default for -drive interface type

[Markus Armbruster]

Block backends defined with -drive if=T, T!=none are meant to be
picked up by machine initialization code: a suitable frontend gets
created and wired up automatically.

if=T drives not picked up that way can still be used with -device as
if they had if=none, but that's unclean and best avoided.  Unused ones
produce an "Orphaned drive without device" warning.

Many machine types default to if=ide, even though they don't actually
have an IDE controller.  A few default to if=scsi, even though they
lack a SCSI HBA.  Change their default to if=none.

While their, fix handling of index and unit for a few boards with AHCI
controllers, and stop auto-creating the thoroughly obsolete lsi SCSI
HBAs for new PC machine types.
