Thanks Julien,
Finally, I am able to run latest Xen 4.9,latest Linux kernel 4.9 and latest
buildroot on orangepi PC and NenoPi-M1 board.
Now,I want to run RTOS VM on Xen and pin the CPU to RTOS VM so i can
achieve real time response from RTOS VM.
Long term I want to do GPU(on Mali) virtualization If anyone have
experience on GPU(on Mali) virtualization on ARM board,Please provide me
some pointer.
following log of xen on orangePi PC board
