QEMU instance with scsi devices for RISC-V ?
- Go to: [ bottom of page ] [ top of archives ] [ this month ]
Date: Tue, 01 Feb 2022 12:38:43 UTC
I am going in tight little circles trying to get more than 8 disks
to be available to a RISC-V instance. However the virtio block device
type seems to be limited to three bits for the device id. That is
just a guess.
I am trying with virtio-scsi-pci type but the LiveCD option does not
see anything other than the installer disk1.iso cdrom image :

Looking at the verbose output from boot I do see a SCSI device listed
there :
virtio_pci0: <VirtIO PCI (legacy) SCSI adapter> port 0x1000-0x103f mem
0x40000000-0x40000fff,0x40004000-0x40007fff irq 26 at device 1.0 on pci0
So the bus id seems to be pci0 but thus far any attempt I have made
simply gets me a LiveCD running with no available SCSI disks.
Is this just a QEMU rabbit hole maze of options problem?
