What we know so far:
- the issue is not related to cloud-init.
- the very high CPU load was atleast partly caused by byobu bug 1208853. To
disable byobu...

i doubt cloud-init has any thing to do with it, other than being the
thing that ran apt (which then some possibly substantial network IO and
disk IO and cpu).

I'm suspecting an issue with nested=1... the nested VM does eventually
boot but it takes many minutes to do so. At this point, the cpu usage of
qemu-kvm drops to reasonable values. But if you ssh into the vm, the
usage jumps up to ~200% again.
To recreate:
$ sudo apt-get install -y genisoimage li
Attempting to repeat the dep8 test run in the same environment has so
far resulted in the qemu-kvm binary consuming 200% CPU (recreated on
multiple nodes).
