Want to compile a kernel, and then use the kernel operation simulator, but always can't normal start, want to know where is the problem?
Aosp compiled with own kernel_ranchu emulator (in the aosp/out/target/product/generic_x86_64) run successfully started, kernel version is 4.14, but run aosp/prebuilts/qemu - kernel/x86 kernel_qemu2 would black screen, shows the two are not the same, then I download the goldfish, compiling a 4.14 kernel, is the x86_64_ranchu_defconfig goldfish, the simulator can start, but can't operation, has been stuck in a desktop, can't shut down, logcat shows , if the compile is the kernel of 4.9, the emulator running is to stay in the android boot animation interface, unable to boot,
Also use aosp/prebuilts/qemu - kernel/build - kernel. Sh the configuration of the test, is a black screen,,,, is made up of kernel_qemu, look from the name and the prebuilt kernel_qemu2 should be the same, so from kernel_qemu2 to kernel_ranchu after what operation?

Online tutorial watched, couldn't solve the problem, have a great god help
