Your distro may have a different name for the required packages. The cloud-utils package is required for Debian 10 to be able to run the cloud-localds command, and the whois package is required for us to be able to run mkpasswd later. We need to ensure we have cloud-utils and whois packages for later. var/lib/libvirt/images/templates/ubuntu-22-server.qcow2 Sudo mv -i jammy-server-cloudimg-amd64.img \ sudo mkdir /var/lib/libvirt/images/templates Create Debian 11 (Bullseye) KVM Guest From Cloud Imageĭownload the Ubuntu 22.04 server cloud Image and rename to qcow2 to save confusion.Create Ubuntu 20.04 KVM Guest From Cloud Image.You should arrive at an Ubuntu login prompt. $ qemu-system-aarch64 -M virt -cpu cortex-a57 -m 2048 \ Run QEMU to boot your newly installed virtual machine, but this time without the install media. drive if=none,id=cd,file=/local/ install-images/ubuntu-20.04- live-server-arm64.isoĪt the boot menu that appears select “Install Ubuntu Server”.įollow the prompts until the installation is complete.Īfter the installation is complete shutdown the virtual machine and QEMU will exit to the host Linux prompt: $shutdown now Boot the newly installed virtual machine drive if=pflash,format=raw,file= flash1.img \ drive if=pflash,format=raw,file= flash0.img,readonly \ drive format=qcow2,file=hda.qcow2, if=none,id=drv0 \ object rng-random,filename=/dev/ urandom,id=rng0 \ device virtio-net-pci,netdev=net0, romfile="" \ We doing a Ubuntu Server install and so everything is console based and there is no GUI. The install image ISO will appear as a CD drive to the virtual machine and will automatically launch the installer. $ qemu-img create -f qcow2 hda.qcow2 16G Boot the virtual machine and run the Ubuntu installer Set up empty disk qcow2 image (16G in this example) where Ubuntu will be installed. Create an empty 64MB flash image to hold UEFI variables. $ cp /usr/share/qemu-efi-aarch64/ QEMU_EFI.fd flash0.imgĢ. Place the UEFI image in a 64MB simulated flash. The UEFI image will be placed in a 64MB simulated flash and an empty simulated 64MB flash will be used for UEFI variable.ġ.
