When trying qemu-x86_64 target with full disk image, grub wasn't able to read the rootfs. After comparing it's config with the one used on my notebook, I was able to get it right.

Apart from fixing the failure, this also enables serial output so grub menu becomes accessible when calling qemu with -nographic option.
