[yocto] adding meta-virtualization gives bitbake error

[Jakob Hasse]

Hello,

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:

bitbake -C compile core-image-base

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.


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).

Thanks and all the best,
Jakob
