[Qemu-discuss] 答复: How to connect megasas to its backend?

[侯雨]

Hi, all,

may I ask a question?

How to write the -drive and -device parameter to specify two files to work as 
two partitions/drivers in qemu? 
I am hoping to use virtio-blk-device, thanks!

Br.

Of course megasas doesn't. Megasas is a SCSI HBA emulation, not a
SCSI device emulation.

You'd have to use two device specifications here:

-drive file=/path/to/image,if=none,id=foo -device megasas,id=raid
-device scsi-disk,drive=foo,serial=1234,bus=raid.0

or

-device scsi-disk,drive=foo,serial=1234,scsi-id=0

Cheers,

Hannes
