Embodiment Construction
[0035] A platform virtualization system provided by the present invention is introduced below in conjunction with the accompanying drawings and embodiments:
[0036] Such as figure 1 As shown, a platform virtualization system runs an X86 architecture virtual machine on a Loongson processor platform, including a CPU emulator, a memory virtualization module, and a peripheral virtualization module.
[0037] (1) CPU simulator
[0038]Running the x86 architecture virtual machine on the Loongson platform, because the x86 architecture virtual machine (virtual machine for short) and the Loongson platform adopt different architectures, the instructions of the virtual machine cannot be directly executed on the physical hardware of the Loongson platform, and must be translated. The code is converted into the code used by the physical machine of the Godson platform.
[0039] The virtualization system (VMM) on the Loongson platform uses full virtualization technology. The virtualization...
