| = Ubuntu installation on a RISC-V virtual machine using a server install image and QEMU = == Overview == Starting with Ubuntu 22.04 a server install image for QEMU is available. This topic describes how to use the image for an installation on a virtual machine. The Jammy release image is available at https://cdimage.ubuntu.com/releases/22.04.2/release/. Daily build images are provided at https://cdimage.ubuntu.com/ubuntu-server/daily-live/current/. A general overview of the installation process is available at https://ubuntu.com/tutorials/install-ubuntu-server 61. == Prerequistites == To run the installation you will need the following packages: * qemu-system-misc - QEMU 18 is used to emulate a virtual RISC-V machine. * u-boot-qemu - U-Boot is the firmware implementing the UEFI API and loads GRUB. {{{ sudo apt-get update sudo apt-get install qemu-system-misc u-boot-qemu }}} Download the image either using your web browser or with {{{ wget https://cdimage.ubuntu.com/ubuntu-server/daily-live/current/jammy-live-server-riscv64.img.gz }}} ==Installation== Extract the image. {{{ gzip -d jammy-live-server-riscv64.img.gz }}} Create the disk image on which you will install Ubuntu. 16 GiB should be enough. {{{ dd if=/dev/zero bs=1M of=disk count=1 seek=16383 }}} Start the installer with: {{{ /usr/bin/qemu-system-riscv64 -machine virt -m 4G -smp cpus=2 -nographic \ -kernel /usr/lib/u-boot/qemu-riscv64_smode/u-boot.bin \ -netdev user,id=net0 \ -device virtio-net-device,netdev=net0 \ -drive file=jammy-live-server-riscv64.img,format=raw,if=virtio \ -drive file=disk,format=raw,if=virtio \ -device virtio-rng-pci }}} Follow the installation steps in https://ubuntu.com/tutorials/install-ubuntu-server. When rebooting we have to remove the installer image. Otherwise the installer will restart. U-Boot gives you a 2 second time window to press the Enter key to reach the U-Boot console. In U-Boot’s console you can use the poweroff command to stop QEMU. Another option to exit QEMU is pressing keys CTRL-a followed by key x. == Run Ubuntu == To run your installed Ubuntu image use {{{ /usr/bin/qemu-system-riscv64 -machine virt -m 4G -smp cpus=2 -nographic \ -kernel /usr/lib/u-boot/qemu-riscv64_smode/u-boot.bin \ -netdev user,id=net0 \ -device virtio-net-device,netdev=net0 \ -drive file=disk,format=raw,if=virtio \ -device virtio-rng-pci }}} = Limitations = In Ubuntu 22.04 the number of virtual CPUs is limited to 8 in QEMU and in the Linux kernel. |
