Custom Kernel Qemu: No Choice for rootfs
I tried creating a custom kernel config, but can't boot now. The qemu command looks like the following:
qemu-system-x86_64 -kernel $KERNEL/arch/x86/boot/bzImage
-append "console=ttyS0 root=/dev/hda debug earlyprintk=serial slub_debug=QUZ"
-drive file=$IMAGE/wheezy.$1.img,format=raw -net user,hostfwd=tcp::10021-:22 -net nic
-enable-kvm -nographic -m 2G -smp 2
And the error message:
[ 1.029707] VFS: Cannot open root device "hda" or unknown-block(0,0): error -6
[ 1.031629] Please append a correct "root=" boot option; here are the available partitions:
[ 1.033696] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
The image boots with other pre-built kernels, so I think I might have missed something in the Kconfig, but don't know what.
