Issue while building the OpenEmbedded filesysytem from source (ARM Versatile Express Juno r2 Development Platform)

Similar to this thread, i'm having some hard time building the openembedded filesystem.

So far I have managed to follow this tutoriall until the "Booting the board" section. After running the board some errors appear during the execution:

Execution of the PuTTY shell (Part 1)

Execution of the PuTTY shell (Part 2)

This lead me to follow the "Addendum B: Building the OpenEmbedded filesysytem from source" 

(I thought this part was optional since in this section "Initialising a workspace" it says "The script will guide you through the process of initialising your workspace, automatically downloading all relevant source files and required binaries.")

I executed this commands with no problems:



But, after running this commands:



I get the following Warnings and Errors (from the log file located in the directory /Desktop/openembedded/build/tmp-glibc/log/cooker)):



The only thing I changed from the original files was that I added "DISTRO_FEATURES_append = " virtualization"" to the /Desktop/openembedded/meta-virtualization/layers.conf. It should be noted, I guess, that I'm running a virtual machine with Ubunto 16.04.1 LTS...executing uname -a gives:
Linux lfpm1993-virtual-machine 4.13.0-39-generic #44~16.04.1-Ubuntu SMP Thu Apr 5 16:43:10 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux


What I need from the development board (ARM Versatile Express Juno r2 Development Platform) is the ability to run PAPI (maximize the number os hardware counters that I have avaiable) and the energy aware scheduler (EAS). The reasson I didn't use a prebuilt build was because of ,according to the kernels tab, the only option that allows EAS is `ack-armlt' and all prebuilt configurations that don't use Android have `latest-armlt'.

So, my question is how do I solve those warnings and errors? if the 'base configuration' is correct, that is if I really need to run the addendum B? And in the case, of if it is 'working' what should I be doing next? (hope I was clear, english is not my native language). 

Thanks for the help,

Luis Martins
