Xen 4.12.2

OBS: You need to set the /bin path (that contains all binaries) into the PATH env variable:
export PATH+=":~/<path_to_workfolder>/poky/bitbake/bin"/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/home/sargx/.local/share/JetBrains/Toolbox/scriptsHere is the output of the build process:
We only care about the two bin images A and B, where A stands for the “Linux Kernel for DOM0” and B stands for the “Xen Image”.
