Did you see configs/x86/qemu-x86.c already? That is supposed to work for the recommended command line and also the start-qemu.sh script from jailhouse-images. There are likely some subtle differences to the config the generator spits out, unfortunately. I haven't tried "config create" on QEMU in a long while, simply because we have a reference config, but maybe there is something that could be improved once you found the relevant differences.
