Tested in Ubuntu 24.04.

# Qemu

Install:

```auto
$ sudo apt install qemu-system-misc u-boot-qemu

```

List 32-bits supported boards:

```auto
$ qemu-system-riscv32 --machine help

```

List 64-bits supported boards:

```auto
$ qemu-system-riscv64 --machine help

```

Download the Ubuntu preinstalled server image:

```auto
$ wget --continue https://cdimage.ubuntu.com/releases/24.04/release/ubuntu-24.04.2-preinstalled-server-riscv64.img.xz

```

Decompress the image:

```auto
$ xz --decompress --keep ubuntu-24.04.2-preinstalled-server-riscv64.img.xz

```

Resize the image:

```auto

$ qemu-system-riscv64 \
    -machine virt \
    -nographic \
    -m 2048 \
    -smp 4 \
    -kernel /usr/lib/u-boot/qemu-riscv64_smode/uboot.elf \
    -device virtio-net-device,netdev=eth0 \
    -netdev user,id=eth0 \
    -device virtio-rng-pci \
    -drive file=ubuntu-24.04.2-preinstalled-server-riscv64.img,format=raw,if=virtio
