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!
Please start your own thread next time.
Simply provide more than one pair of --device and --drive
options, one for each virtual drive.
If using virtio-blk-device, there is no option for a
virtual SCSI adapter, otherwise multiple drives can share
a single SCSI adapter.

Hi,
For nvme, it uses "drive=" property to connect to backend.
-drive file=/path/to/image,if=none,id=foo -device nvme,drive=foo,serial=1234
But megasas doesn't have "drive" property.
Could you share qemu commands to connect megasas device to its backend drive?
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
Enjoy
