Expected Behavior: 12 arm core with 6MB L3 cache

[lix19937]

The Linux OS is running on top of a Type1 Hypervisor. And the hardware resources (CPU core, cache...) that can be accessed by the guest OS is allocated by the hypervisor.
Based on the current configuration, the Linux OS can only access to 11 CPU core and 4M L3 cache. This is what we expected.
