* Size:
$ du -s tmp/deploy/images/qemux86/bzImage*
2664 
tmp/deploy/images/qemux86/bzImage--4.4.3+git0+770996a263_73481a3abd-r0-qemux86-20160411015757.bin
2572 
tmp/deploy/images/qemux86/bzImage--4.1.18+git0+b9023d4c8f_f5b08e95bc-r0-qemux86-20160411022834.bin

We can see that 4.1 and 4.4 are nearly the same (92K different).

And:
$ runqemu qemux86 ramfs
works well. Please see the boot logs in the attachment.

And poky-tiny only supports qemux86 + cpio.gz atm, I've filed two enhancements
for YP 2.2 to support more machines and fs types:
