ACRN-Hypervisor build fail


          I am facing the build failure when trying to build acrn-hypervisor. I have generated the board.xml and scenario.xml file as given in the procedure.
I am using kontron board which belongs to intel apollo lake APL0. I am attaching the board.xml file and scenaio xml file.

Previously, i have removed those lines to suppress the warnings and built the acrn and kernel. User vm is able to launch and worked perfectly. 
My question is are these configurations mandatory for running the user vm without any problem in future. If not, how to fix them.
