Hello Bruce,

Thank you for the advice with the morty branch, this worked perfectly.

Now, however, docker is installed on my Yocto-system but I can't run it:

~# docker
-sh: /usr/bin/docker: No such file or directory

Is "docker" the client to control and run containers (e.g. "docker run hello-world")? On my Ubuntu machine, this works, I installed docker and docker.io via apt, then I could run "docker run hello-world".

All the Best and many thanks in advance!

we're trying to include meta-virtualization in to our project, in particular, we want to use docker. However, as soon as I include the layer in to our project, bitbake complains:

Do we need to checkout a specific branch or so (though I can't find one right now)? Do we need to change some kernel configuration? I added all virtualization drivers in the "drivers" section of the kernel config already.

We're using DIGI embedded Yocto 2.2 (poky).

You need to check out the matching branch to the release you've
been given as an enablement, since some of the APIs, etc, have
changed and the meta-virt sanity check that was added later than
the 2.2 release isn't working.

2.2 was the 'morty' release, and meta-virt does have a branch for

    python-*: use https for pypi URLs

    Several of the recipes here were using http URLs for source hosted on
    pypi - pypi apparently no longer supports http so switch to https

    Apply this commit [1] to morty branch.
