- Use the kprobe method to capture the return value of handle_cpuid, and determine whether #VE or #GP is triggered based on the return value.
- Also can modify the detection functions, such as hanlde_cpuid, read_msr, write_msr, handle_mmio, handle_io, etc. Only need to modify the value of .kp.symbol_name.
