kas-docker does not seem to work when binfmt misc uses different configuration on host #19

Closed cgerum closed 4 years ago

When trying to run kas-docker I got the following error message:

| I: Running command: chroot /work/build/tmp/work/jailhouse-demo-arm64/isar-bootstrap-target/1.0-r0/rootfs /debootstrap/debootstrap --second-stage
| chroot: failed to run command ‘/debootstrap/debootstrap’: No such file or directory
| WARNING: exit code 127 from a shell command.
| 
ERROR: Task (mc:qemu-arm64-jailhouse-demo:/work/isar/meta/recipes-core/isar-bootstrap/isar-bootstrap-target.bb:do_bootstrap) failed with exit code '1'

The cause of the error was not that debootstrap/debootstrap was actually missing, but that /proc/sys/fs/binfmt_misc/qemu-aarch64 contained the wrong path to the qemu-interpreter. Due to a different binfmt-support setup on the host.

I don't know wether this is actually solvable in kas-docker, but at least this ticket might help somone to find the cause of the error.

In general we do not do issues, you should use the mailing list for questions, bug reports and patches.

You should try https://github.com/siemens/jailhouse-images and see if that works for you. My first guess is that you did not run kas-docker with --isar, which is required to set up binfmt and choose the right container with everything you need for an isar build.
