Cover letter [Qemu-devel] [PATCH 0/7] Add -disk interface

This series of patches add a new interface to qemu to define storages.

The new parameter is "-disk":

    -disk file[,if=type][,index=i][,bus=n][,unit=m][,media=d][,cyls=c,heads=h,secs=s[,trans=t]][snapshot=on|off]

where:

file is the disk image
type is the interface type (ide, scsi, floppy, pflash, mtd, sd) i is the index of the disk on the interface (0, 1, 2, ...) n is the bus number of the given type
m is the unit number on the the given bus
d is the type of the media (disk, cdrom)
c,h,s,t are the parameters usually given by -hdachs snapshot allows to enable or not the snapshot for this disk

"-cdrom file" is an alias for "-disk file,index=2,media=cdrom" "-hda file" is an alias for "-disk file,index=0,media=disk" "-hdb file" is an alias for "-disk file,index=1,media=disk" "-hdc file" is an alias for "-disk file,index=2,media=disk" "-hdd file" is an alias for "-disk file,index=3,media=disk" "-hda file -hdachs a,b,c" is an alias for

                 "-disk file,index=0,cyls=a,heads=b,secs=c"

"-fda file" is an alias for "-disk file,index=0,if=floppy" "-fdb file" is an alias for "-disk file,index=1,if=floppy" "-pflash file" is an alias for "-disk file,if=pflash" "-mtdblock file" is an alias for "-disk file,if=mtd" "-sd file" becomes the alias of "-disk file,if=sd"

You can also define a cdrom on the slave of ide0 with:
"-disk file,if=ide,bus=0,unit=1,media=cdrom" You can define a cdrom on the scsi bus 0 with unit id 3:
"-disk file,if=scsi,bus=0,unit=3,media=cdrom"

You can define a scsi disk on bus 0 with unit id 6 with:

"-disk file,if=scsi,bus=0,unit=6"

You can define disks with default ordering:

"-disk a.img -disk b.img -disk c.img" is equal to "-hda a.img -hdb b.img -hdc c.img"
