Hi. I'm afraid this doesn't build on 32-bit hosts:

CC hw/virtio/virtio-rng.o
/root/qemu/hw/virtio/virtio-rng.c: In function 'virtio_rng_device_realize':
/root/qemu/hw/virtio/virtio-rng.c:186:19: error: format '%lld' expects
argument of type 'long long int', but argument 7 has type 'long int'
[-Werror=format]
cc1: all warnings being treated as errors

I think you want "(int64_t)0" rather than "0L".

thanks
