Hi Duc Anh, I'm not sure the setup laid out in the tutorial would work for arm system as we only tested it on x86 arch. However, I believe there are forks of packer that would work with arm arch (https://www.packer.io/community-tools), and there are also tutorials for using packer to build disk images for arm devices, such as Raspberry Pi.
arm also provides documentation of building Linux kernels (https://www.gem5.org/documentation/general_docs/fullsystem/building_arm_kernel) as well as offers built disk images/Linux kernels(https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries).
