Help¶

A 64-bit integer indicating the base physical address where the hypervisor should be loaded. If RELOC is disabled, the bootloader is required to load the hypervisor to this specific address. Otherwise the hypervisor will not boot. With RELOC enabled the hypervisor may relocate its symbols to where it is placed, and thus the bootloader might not place the hypervisor at this specific address. Note that the addr demands 2M aligned, otherwise memory corruption may occur.
