[PATCH v2 5/7] launch: direct: Remove dead code promising we were going to use virtio-console.

[PATCH v2 0/7] tests/qemu: Add program for tracing and analyzing boot times.
v1 was here:
https://www.redhat.com/archives/libguestfs/2016-March/thread.html#00157

At the moment, about 50% of the time is consumed by SeaBIOS. Of this,
about ⅓rd is SGABIOS
