I am trying to add the meta-virtualization layer in my yocto project. The layer depends on openembedded-core and multiple layers provided by meta-openembedded. Following is the structure of my bblayers.conf file after adding the meta-virtualization layer and it’s dependencies.
BBLAYERS ?= " /home/mshehery/Downloads/git/Yocto/poky/meta /home/mshehery/Downloads/git/Yocto/poky/meta-yocto /home/mshehery/Downloads/git/Yocto/poky/meta-yocto-bsp /home/mshehery/Downloads/git/Yocto/poky/meta-oe /home/mshehery/Downloads/git/Yocto/poky/meta-virtualization /home/mshehery/Downloads/git/Yocto/poky/meta-networking /home/mshehery/Downloads/git/Yocto/poky/meta-filesystems /home/mshehery/Downloads/git/Yocto/poky/meta-python "
However, when I try to build docker present in the meta-virtualization layer, I encounter the following error
WARNING: Host distribution "Ubuntu-16.04" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution. Loading cache: 100% |####################################################################################################################################################| ETA: 00:00:00 Loaded 1078 entries from dependency cache.

If I am not wrong, the current versions of the yocto project use openembedded as their build system. So, is there any need to integrate the openembedded-core into my yocto project to add the meta-virtualization layer, or is it already present in the yocto project by default?

Short summary of the discussion:
Use the same release branch for all your layers (unless you really know what you do.
Check that all your layers are activated in
bblayers.conf.
