Forgot to mention some things:

1. Feedback if the whole setup works for others would be very welcome!

2. This actually stresses yet another OSS project of us: kas [2]. It's
   being used for Isar layer configuration management and bitbake setup
   along with its build container kasproject/kas-isar for Isar.

3. One already planned feature for jailhouse-images is support for a
   qemu-amd64 image, probably also stressing qemu-static vs. cross build
   support.

We could also include support for bootable images of some of our
reference boards at some point, but we will need some more tuning on
Isar for that first (on wic in particular). And, eventually, this
builder could spit out images for automated tests as well.
