Do you know if qemu can accept other type of images for the kernel
and rootfilesystem?

At the moment, my yocto core-image-minimal and 
core-image-sato builds the following files, if I first
build with machine ?= "virtex5", and then subsequently
with machine ?= "qemuppc"

vmlinux-qemuppc.bin

Is it possible to use uImage-virtex5.bin for the kernel image and core-image-minimal-virtex5.tar.gz as the kernel image and rootfilesystem, instead of vmlinux-qemuppc.bin and core-image-sato-qemuppc.ext3 ?
