Problems with my own Kernelconfig and Qemu


Hello together,

About me:
at the moment I´m doing my first project with Embedded Systems.
For this I bought the book: Embedded Linux from Jürgen Quade.
There are some tutorials in, which Iḿ doing at the moment (Tutorials with Kernel 3.10... not current)

So my problem at this:
Till now I have configured the Linux Kernel 5.2.4 . And now I wants to test this Kernel with Qemu.

My development PC:

  • ElementaryOS (Ubunu 18.04)
  • 64 bit

I start Qemu with this command:
alex@ElementaryWork:~/Dokumente/02_Entwicklung/08_RaspberryPi/embedded/qemu$ qemu-system-x86_64 -kernel linux-5.2.4/arch/x86/boot/bzImage

I get this output:
qemu-system-x86_64: warning: TCG doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5]

After this Qemu opens and brings the message:
Booting from ROM.... and then nothing happens!

Do you have any idea, what the problem could be?

Thank you very much!

Yours sincerely
