Hi, I loaded an incorrect BIOS before which is why I was getting all those errors, After I loaded the correct BIOS it's all working fine, I can build my root cell configuration file now.

Alright so I refreshed my flash drive and the BIOS too yesterday , I can 'make' and thus obtain the jailhouse kernel module and the image as well. However when I try to run 'tools/jailhouse config create -r myboard/ configs/myboard.c', it says that I need Intel IOMMU enabled on target linux whereas I have already done that. What I then did was disabled VT-d in the BIOS and tried to run 'tools/jailhouse config collect data.tar' to see if it gives "DMAR: No such file or directory" , It should give this error as I have disabled VT-d however it did not! , that's the new twist in here which means it can run the collect script even if VT-d is disabled! So my suspect is the DMAR which should have some connection with the BIOS.

Just repeat what you already did successfully.
