Can't run a guest OS using QEMU in host Ubuntu

Issue

I'd like to run a Debian OS .iso image for ARM processors using QEMU in a host running Ubuntu (over an x86 architecture).

I executed the following line in a terminal:

aaron@aaron-HP-ZBook-14:~/Descargas$ qemu-system-arm -machine sabrelite -cdrom debian-10.7.0-arm64-netinst.iso -m 1024

But then, the following window appears.

I don't know why Debian OS is not initiating after executing the previous line. Instead, a QEMU command line interface appears waiting for the user to enter some commands.

Thanks in advance!

Aarón.

Solution

Generally if you try to run qemu and only see the monitor there is likely something wrong with your image.

In this case you are attempting to boot "debian-netinst" which is the debian network-install image. If you want to emulate a debian-arm image I would recommend following this tutorial to get debian-arm up and running.

Here is a script that will automate the process in that tutorial

The script runs two QEMU commands. The first is a lengthy install process that should extract a debian initrd/kernel. The second QEMU command will boot the actual image. After the second command runs you should see the QEMU monitor open in a window. Use ctrl+alt+(1 or 2) to switch to the terminal/gui display
