The virt machine has IF_VIRTIO as block_default_type, which causes the generic code to try to create a virtio-blk-pci device pair at configure_blockdev()/qemu_create_cli_devices().
Select VIRTIO_BLK and VIRTIO_PCI from CONFIG_ARM_VIRT to avoid errors when PCI_DEVICES=n (due to e.g. --without-default-devices): $ ./qemu-system-aarch64 -M virt -accel tcg -cpu max -nodefaults -cdrom foo.qcow2 qemu-system-aarch64: -cdrom foo.qcow2: 'virtio-blk' (alias 'virtio-blk-pci') is not a valid device model name Signed-off-by: Fabiano Rosas <faro...@suse.de> --- hw/arm/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/hw/arm/Kconfig b/hw/arm/Kconfig index 8dcc08b7ec..296d4f5176 100644 --- a/hw/arm/Kconfig +++ b/hw/arm/Kconfig @@ -33,6 +33,7 @@ config ARM_VIRT select ACPI_HMAT select VIRTIO_PCI select VIRTIO_NET + select VIRTIO_BLK config CHEETAH bool -- 2.35.3
