We can also install from a debain iso. A sample installation is as follows:

qemu-system-aarch64 -M virt -enable-kvm -cpu host,aarch64=off -smp 2 -m 2048 \
-device nec-usb-xhci -device usb-kbd -device usb-mouse -usb -serial stdio \
-device usb-storage,drive=install -drive file=debian-10.8.0-armhf-xfce-CD-1.iso,if=none,id=install,media=cdrom,readonly=on \
-drive if=none,file=hda3.qcow2,format=qcow2,id=hd -device virtio-blk-device,drive=hd \
-device virtio-gpu-pci,virgl=on,xres=1600,yres=900 -display sdl,gl=on \
-nic user,model=virtio -bios edk2-arm-code.fd

If you can download the installation iso, an example setup can be done as follows:

qemu-system-aarch64 -M virt -enable-kvm -cpu host -smp 2 -m 2048 \
-device nec-usb-xhci -device usb-kbd -device usb-mouse -usb -serial stdio \
-device usb-storage,drive=install -drive file=debian-10.8.0-arm64-xfce-CD-1.iso,if=none,id=install,media=cdrom,readonly=on \
-drive if=none,file=hda3.qcow2,format=qcow2,id=hd -device virtio-blk-device,drive=hd \
-device virtio-gpu-pci,virgl=on,xres=1600,yres=900 -display sdl,gl=on \
-nic user,model=virtio -bios edk2-aarch64-code.fd

Oh. Those files are on partition 1 rather than 2!
Now I am able to run with KVM and its really fast. Its an armhf guest now on aaarch64

Now to figure out how to get a GUI to work with GPU acceleration..

There is one more point about the virt machine. Mostly its the only one that supports directly the KVM and thats what I am using now.

Here is how I am trying to install an armhf guest on an aarch64 machine (in my case jetson nano).

../qemu/build/qemu-system-aarch64 -M virt -m 2048 -smp 2 -cpu host,aarch64=off -enable-kvm -kernel installer-vmlinuz -initrd installer-initrd.gz -drive if=none,file=hda.qcow2,format=qcow2,id=hd -device virtio-blk-device,drive=hd -netdev user,id=mynet -device virtio-net-device,netdev=mynet -nographic -no-reboot

Its working fine and I am able to install, though I dont know why bootloader installation fails.
And when I continue without boot loader, and try to see the boot folder in hda.qcow2 no files are present!

In reply to notinaboat.

I created an issue on the script you built. I couldn’t make these instructions to work. Maybe you could take a look at there! Thanks

Thanks Peter! I’m no longer shouting “256MB os not enough!” at `versatilepb`:)

I have posted a Makefile for installing “buster” based on your instructions here: https://github.com/notinaboat/qemu_debian_armhf

Hi,

Is it possible to pass through the USB to QEMU command line for ARM machines, am using virt machine.
I added by using this command “-usb -device usb-host,hostbus=,hostaddr=” but its working for x86 QEMU machine not for ARM virt machine.

Any help?

Thanks,
Srinuvasan.A

Hey,
I know it’s a noob question, but how to connect to the vm using `ssh` ?

Regards

Thanks a lot! Hopefully, now I can build and debug Raspberry Pi programs easily on my PC which is light years more powerful than that fan-less machine :)

hi,I have a question on qemu virt,I want to load a arm64 kernel on virt using the command “emu-system-aarch64 -machine virt,virtualization=true,secure=true -cpu cortex-a53 -m 1G -smp 2 -kernel ./build/EAOS64.bin -nographic -s -S” ,but I got the wrong EL,the value I read from the register CurrentEL is 0x8,not 0xC.what is wrong with my command?Thanks for your help.
