问题
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.

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

You're trying to boot a 64-bit Arm CDROM image on a board which is 32-bit only, so this is never going to work.
More generally, most Arm boards will not simply boot from a CDROM image passed via the -cdrom option, because they don't have firmware/BIOS images which will run on QEMU and do the handling of booting from CD. Many boards don't even have an IDE or SCSI interface that a CDROM drive could be plugged into!
You should decide whether you want (a) to boot an image on the sabrelite board, (b) to boot a 32-bit arm image, but you don't care which board (c) to boot an arm64 kernel, and find a suitable tutorial or set of instructions accordingly. Lenna's link is good for option (b); there's a similar tutorial also for option (c). I don't know of any sabrelite specific instructions.
It's worth reading the QEMU documentation section on choosing an Arm board model -- unless you have a strong reason why you want to use a particular board model and a kernel that you know works on that board model, then 'virt' is usually a better choice. Even 'virt' won't boot directly off a cdrom, though, unless you also pass it a suitable UEFI bios image.
