+# Qemu ARM64
+
+How to run QEMU with various ARM64 images.
+Not covering full blown support of each distribution. Goal is just to get to Linux shell
+and no more further at this stage.
+
+## Run Ubuntu Image
+
+```bash
+wget -c https://cdimage.ubuntu.com/releases/22.04/release/ubuntu-22.04.3-live-server-arm64.iso
+```
+
+
+## Run Debian Image
+
+```bash
+wget -c http://http.us.debian.org/debian/dists/bookworm/main/installer-arm64/current/images/netboot/debian-installer/arm64/initrd.gz
+wget -c http://http.us.debian.org/debian/dists/bookworm/main/installer-arm64/current/images/netboot/debian-installer/arm64/linux
+```
+
+Prepare qemu empty hdd image
+
+```bash
+qemu-img create -f qcow2 hda.qcow2 5G
+```
+
+Boot image and follow installation steps. That will install Debian ARM64 distribution
+
+```bash
+qemu-system-aarch64 -M virt -m 1024 -cpu cortex-a53 \
+ -kernel linux \
+ -initrd initrd.gz \
+ -drive if=none,file=hda.qcow2,format=qcow2,id=hd \
+ -device virtio-blk-pci,drive=hd \
+ -netdev user,id=mynet \
+ -device virtio-net-pci,netdev=mynet \
+ -nographic -no-reboot
+```
+
+get guestfs-tools to make below commands work [https://libguestfs.org/](https://libguestfs.org/)
+
+find vmlinuz and initrd names in /boot directory
+
+```
+virt-ls -a hda.qcow2 /boot
+virt-copy-out -a hda.qcow2 /boot/vmlinuz-6.1.0-12-arm64 /boot/initrd.img-6.1.0-12-arm64 .
+```
+
+Boot qemu with installed debian arm64 image
+
+```
+qemu-system-aarch64 -M virt -m 1024 -cpu cortex-a53 \
+ -kernel vmlinuz-6.1.0-12-arm64 \
+ -initrd initrd.img-6.1.0-12-arm64 \
+ -append 'root=/dev/vda2' \
+ -drive if=none,file=hda.qcow2,format=qcow2,id=hd \
+ -device virtio-blk-pci,drive=hd \
+ -netdev user,id=mynet \
+ -device virtio-net-pci,netdev=mynet \
+ -nographic
+```
+
+## Run Archlinux
+
+```bash
+wget -c http://os.archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz
+```
+
+## Create custom images
+
+```
+
+```
+
+### Create kernel
+
+```
+
+```
+
+### Create initrd or rootfs
+
+find . -print0 | cpio --null -ov --format=newc > ../initramfs.cpio
+zstd initramfs.cpio
+
+List content of cpio
+
+lsinitcpio initramfs.cpio
+
+
+### Unpack initrd
+
+## Run virt
+
+Qemu contains configuration to run non existent machine called virt that suppose to be run with virtual machines.
+
+```bash
+```
+
+
+## Under ArchLinux
+
+Install all qemu packages with
+
+```bash
+pacman -S qemu-full
+```
+
+
