[Qemu-discuss] How to get Base IO address for config drive file

[Meganathan Raja]

Hi All,

I tried to read configuration file in my real time operating system passed by qemu-kvm. The configuration drive format as ISO 9660. When I tried reading configuration file using ATA/IDE driver with bus id as zero and drive id as one, the recalibration of device has failed. So I tried using SCSI driver with base IO address as 0x330 and IRQ number as 0xB, device sense has failed.

Please let  me know the base IO address and IRQ number passed by qemu-kvm for the ISO 9660 device using the config drive option.
