Test script below. "qemu-default" is a wrapper script which starts
qemu-system-x86_64 from my build directory. "qemu-firmware" is the
same plus isa-debugcon configured for a firmware log on stdout.
Latest bits (with some of the review comments addressed) just pushed
to git://git,kraxel.org/qemu sirius/microvm
