And why not a shorted and more standard solution?

-ideN [hd:|cd:]filename

Examples:

-ide0 /tmp/myimage.dsk
Set primary master as harddisk (hd: is the default)

-ide1 hd:/tmp/myimage.dsk
Set primary slave as harddisk (hd: is not necessary in this case, as
it's the default).

-ide3 cd:/dev/cdrom
Set secondary slave as cdrom using device /dev/cdrom

-ide0 cd:/tmp/myimage.iso
Set primary master as cdrom using an ISO image file.

Of course, the previous parameters (hda, hdb, hdc, hdd and cdrom)
should be also available for compatibility reasons.

And you could also add -fd0 (for -fda) and -fd1(for -fdb) for
consistency with the rest of parameters.

Just my two cents.

And what about non-PC guest environments like Sparcs where there are no IDE
drives, only SCSI ones for hard disk, CD and (I think) for floppy drives ?
How would you expand that syntax ?

Not everyone running QEMU is seeking to run a "PC in PC" configurations.

[Qemu-devel] cdrom hardcoded index

[drtyc]

Hello.

How about finally not having cdrom hardcoded? Right now installing some distro that reqires hda and hdc to be active raid components and having to change that single variable initialization vaue is easy but not comfortable enough with recompiling the qemu...

Someone tried this already with qemu-flex_cd.patch but looking at it now it will require some changes to apply...

Thanks.

not speaking about more then one images as cdrom

Jim sent a patch that works beautifully,
it adds -cdrom-[a,b,c,d] and even gives ability to have multiple cdrom drives.

Its vl.multicdrom, and you can download it from the archives at :

Have fun.

A VM configuration file will be added in QEMU very soon. People wishing 
to have weird hardware setups will have to use it. I am not sure it is 
necessary to complicate the command line syntax for very specific cases.
