In the current design, logic partition scenario is supported on KBL NUC i7 since there is no related configuration and no the cooresponding boot loader supporting. The boot loader supporting is done in the previous patch. Add some configurations such physical PCI devices information, virtual e820 table etc for KBL NUC i7 to enable logical partition scenario. In the logical partition of KBL NUC i7, there are two pre-launched VM, this pre-launched VM doesn't support local APIC passthrough now. The hypervisor is booted through GRUB. TODO: In future, Local APIC passthrough and some real time fetures are needed for the logic partition scenario of KBL NUC i7.
