Can't find kvmconfig and no AFL status screen

Hi,dear blogger:
I can not run the "make kvmconfig" command and I did not find it in Makefile. I don't know whether it will affect my later operation. And is there a AFL status screen after the command "./virtme/virtme-run --rw --pwd --kimg linux/arch/x86/boot/bzImage --memory 512M --script-sh "echo core > /proc/sys/kernel/core_pattern; ./AFLplusplus/afl-fuzz -i ./inp -o ./out -- ./fuzznetlink --dmesg dmesg.txt"". I have noting shown on my screen. I don't know is there something wrong with my operation.

The method to fuzz the linux kernel really work! It can start fuzz the kernel. As for my problem, I use make kvm_guest.config to replace it. What I want to emphasize is that is configure must be right. It is very important. And last thank the author's idea and work!

Dear:
Hello, your method has perfectly solved my problem, but I have another issue where I ran for over an hour and didn't find any crashes. Is this my problem with AFL? Thank you
