Run AxVisor on QEMU AArch64

目前，在 QEMU AArch64 平台上已经对独立运行 ArceOS 和 Linux 以及同时运行 ArceOS + Linux 的情况进行了验证。

ArceOS

准备 ArceOS 镜像

获取 ArceOS 主线代码 git clone https://github.com/arceos-org/arceos.git
在 arceos 源码目录中执行 make PLATFORM=aarch64-qemu-virt SMP=1 A=examples/helloworld 获得 examples/helloworld/helloworld_aarch64-qemu-virt.bin

从文件系统加载运行

获取 AxVisor 主线代码 git clone git@github.com:arceos-hypervisor/axvisor.git，然后在 axvisor 源码目录中执行如下步骤：

制作一个磁盘镜像文件，并将 ArceOS 客户机镜像放到磁盘镜像文件系统中
1. 使用 make disk_img 命令生成一个空的 FAT32 磁盘镜像文件 disk.img
2. 手动挂载 disk.img，然后将ArceOS 客户机镜像复制到该文件系统中即可
```
$ mkdir -p tmp
$ sudo mount disk.img tmp
$ sudo cp /path/to/helloworld_aarch64-qemu-virt.bin tmp/
$ sudo umount tmp
```
修改对应的 ./configs/vms/arceos-aarch64.toml 文件中的配置项
- image_location="fs" 表示从文件系统加载
- kernel_path 指出内核镜像在文件系统中的路径
- entry_point 指出内核镜像的入口地址。必须与上面构建的 ArceOS 内核镜像的入口地址一致
- kernel_load_addr 指出内核镜像的加载地址。默认与 entry_point 一致
- 其他

执行 make ACCEL=n ARCH=aarch64 LOG=info VM_CONFIGS=configs/vms/arceos-aarch64.toml FEATURES=page-alloc-64g APP_FEATURES=fs run 构建 AxVisor，并在 QEMU 中启动。

从内存加载运行

获取 AxVisor 主线代码 git clone git@github.com:arceos-hypervisor/axvisor.git，然后在 axvisor 源码目录中执行如下步骤：

修改对应的 ./configs/vms/arceos-aarch64.toml 中的配置项
- image_location="memory" 配置项
- kernel_path 指定内核镜像在工作空间中的相对/绝对路径
- entry_point 指出内核镜像的入口地址。必须与上面构建的 ArceOS 内核镜像的入口地址一致
- kernel_load_addr 指出内核镜像的加载地址。默认与 entry_point 一致
- 其他

执行 make ACCEL=n ARCH=aarch64 LOG=info VM_CONFIGS=configs/vms/arceos-aarch64.toml FEATURES=page-alloc-64g run 构建 AxVisor，并在 QEMU 中启动。

NimbOS

准备 NimbOS 镜像

NimbOS 仓库的 release 页面已经编译生成了可以直接运行的 NimbOS 二进制镜像文件压缩包：

不带 _usertests 后缀的 NimbOS 二进制镜像包中编译的 NimbOS 启动后会进入 NimbOS 的 shell，本示例启动的就是这个 NimbOS
带 usertests 后缀的 NimbOS 二进制镜像压缩包中编译的 NimbOS 启动后会自动运行用户态测例用于测试，这个镜像用于 AxVisor 的CI测试，见 setup-nimbos-guest-image/action.yml

从文件系统加载运行

获取 AxVisor 主线代码 git clone git@github.com:arceos-hypervisor/axvisor.git，然后在 axvisor 源码目录中执行如下步骤：

制作一个磁盘镜像文件，并将客户机镜像放到文件系统中

使用 make disk_img 命令生成一个空的 FAT32 磁盘镜像文件 disk.img

手动挂载 disk.img，然后拉取并解压二进制镜像

$ mkdir -p tmp
$ sudo mount disk.img tmp
$ wget https://github.com/arceos-hypervisor/nimbos/releases/download/v0.7/aarch64.zip  
$ unzip aarch64.zip # 得到 nimbos.bin
$ sudo mv nimbos.bin tmp/nimbos-aarch64.bin
$ sudo umount tmp

直接使用 configs/vms/nimbos-aarch64.toml 文件中的配置项
- image_location="fs" 表示从文件系统加载
- kernel_path 指出内核镜像在文件系统中的路径
- entry_point 指出内核镜像的入口地址
- kernel_load_addr 指出内核镜像的加载地址
执行 make ACCEL=n ARCH=aarch64 LOG=info VM_CONFIGS=configs/vms/nimbos-aarch64.toml FEATURES=page-alloc-64g APP_FEATURES=fs defconfig 创建 .axconfig.toml 配置文件

执行 make ACCEL=n ARCH=aarch64 LOG=info VM_CONFIGS=configs/vms/nimbos-aarch64.toml FEATURES=page-alloc-64g APP_FEATURES=fs run 构建 AxVisor，并在 QEMU 中启动。

从内存中加载运行

参考别的 guest VM 的运行指导，修改对应的 ./configs/vms/nimbos-aarch64.toml 中的配置项即可：

将 image_location 配置项修改为 image_location="memory"
并设置 kernel_path 为 nimbos 二进制内核镜像在工作空间中的相对/绝对路径

Linux

准备 Linux 镜像

获取 Linux 主线代码 git clone git@github.com:arceos-hypervisor/linux-6.2.0.git
在 Linux 源码目录中执行 make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig，再执行 make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc) 以获取 Image

从文件系统加载运行

获取 AxVisor 主线代码 git clone git@github.com:arceos-hypervisor/axvisor.git，（axvisor通过fs启动linux暂未合并主线，若想尝试可切换至dev/dyn分支），然后在 axvisor 源码目录中执行如下步骤：

执行 dtc -I dts -O dtb -o linux-qemu.dtb configs/vms/linux-qemu.dts 编译 Linux 客户机需要使用的设备树文件 linux-qemu.dtb
执行 make ubuntu_img ARCH=aarch64 制作一个简单的根文件系统镜像 disk.img 作为 Linux 客户机启动之后的文件系统，然后手动挂载 disk.img，然后将 Image 和 linux-qemu.dtb 复制到该文件系统中
```
$ mkdir -p tmp
$ sudo mount disk.img tmp
$ sudo cp /path/to/Image tmp/boot/
$ sudo cp linux-qemu.dtb tmp/boot/
$ sudo umount tmp
```
修改对应的 ./configs/vms/linux-qemu-aarch64.toml 文件中的配置项
- image_location="fs" 表示从文件系统加载
- kernel_path 指出内核镜像在文件系统中的路径
- entry_point 指出内核镜像的入口地址
- kernel_load_addr 指出内核镜像的加载地址
- 其他

执行 make ARCH=aarch64 VM_CONFIGS=configs/vms/linux-qemu-aarch64.toml LOG=info NET=y FEATURES=page-alloc-64g,bus-mmio,ext4fs BUS=mmio APP_FEATURES=fs MEM=8g BLK=y run 构建 AxVisor，并在 QEMU 中启动。

从内存加载运行

获取 AxVisor 主线代码 git clone git@github.com:arceos-hypervisor/axvisor.git，然后在 axvisor 源码目录中执行如下步骤：

执行 make ubuntu_img ARCH=aarch64 制作一个简单的根文件系统镜像 disk.img 作为 Linux 客户机启动之后的文件系统
修改对应的 ./configs/vms/linux-qemu-aarch64.toml 中的配置项
- image_location="memory" 配置项
- kernel_path 指定内核镜像在工作空间中的相对/绝对路径
- entry_point 指出内核镜像的入口地址
- kernel_load_addr 指出内核镜像的加载地址
- 其他

执行 make ARCH=aarch64 VM_CONFIGS=configs/vms/linux-qemu-aarch64.toml LOG=debug BUS=mmio NET=y FEATURES=page-alloc-64g MEM=8g run 构建 AxVisor，并在 QEMU 中启动。

ArceOS + Linux

准备相关镜像

首先，根据以上两个章节的介绍分别制作 helloworld_aarch64-qemu-virt.bin、Image 及 linux-qemu.dtb 镜像文件

从文件系统加载运行

获取 AxVisor 主线代码 git clone git@github.com:arceos-hypervisor/axvisor.git，然后在 axvisor 源码目录中执行如下步骤：

执行 make ubuntu_img ARCH=aarch64 制作一个简单的根文件系统镜像 disk.img 作为 Linux 客户机启动之后的文件系统，然后手动挂载 disk.img，然后将 Image 和 linux-qemu.dtb 复制到该文件系统中
```
$ mkdir -p tmp
$ sudo mount disk.img tmp
$ sudo cp /path/to/Image tmp/boot/
$ sudo cp linux-qemu.dtb tmp/boot/
$ sudo cp /path/to/helloworld_aarch64-qemu-virt.bin tmp/boot/
$ sudo umount tmp
```
修改对应的 ./configs/vms/linux-qemu-aarch64-vm2.toml 和 ./configs/vms/arceos-aarch64.toml 中的配置项
- image_location="fs" 表示从文件系统加载
- kernel_path 指出内核镜像在文件系统中的路径
- entry_point 指出内核镜像的入口地址
- kernel_load_addr 指出内核镜像的加载地址
- 其他

执行 make ARCH=aarch64 VM_CONFIGS=configs/vms/arceos-aarch64.toml:configs/vms/linux-qemu-aarch64-vm2.toml LOG=info BUS=mmio NET=y FEATURES=page-alloc-64g MEM=8g SECOND_SERIAL=y SMP=2 run 构建 AxVisor，并在 QEMU 中启动。此时，终端将阻等待 Telnet 命令

qemu-system-aarch64 -m 8g -smp 2 -cpu cortex-a72 -machine virt,virtualization=on,gic-version=2 -kernel /home/zcs/WORKSPACE/arceos_hypervisor/axvisor/axvisor_aarch64-qemu-virt-hv.bin -device virtio-blk-device,drive=disk0 -drive id=disk0,if=none,format=raw,file=disk.img -device virtio-net-device,netdev=net0 -netdev user,id=net0,hostfwd=tcp::5555-:5555,hostfwd=udp::5555-:5555 -nographic -machine virtualization=on,gic-version=2 -serial mon:stdio -serial telnet:localhost:4321,server
qemu-system-aarch64: -serial telnet:localhost:4321,server: info: QEMU waiting for connection on: disconnected:telnet:127.0.0.1:4321,server=on

启动另一个终端，然后执行 telnet localhost 4321，上一个终端将继续运行，并输出第一个虚拟机启动信息，第二个虚拟机启动信息将在当前终端输出。

从内存加载运行

获取 AxVisor 主线代码 git clone git@github.com:arceos-hypervisor/axvisor.git，然后在 axvisor 源码目录中执行如下步骤：

执行 make ubuntu_img ARCH=aarch64 制作一个简单的根文件系统镜像 disk.img 作为 Linux 客户机启动之后的文件系统
修改对应的 ./configs/vms/linux-qemu-aarch64-vm2.toml 和 ./configs/vms/arceos-aarch64.toml 中的配置项
- image_location="memory" 配置项
- kernel_path 指定内核镜像在工作空间中的相对/绝对路径
- entry_point 指出内核镜像的入口地址
- kernel_load_addr 指出内核镜像的加载地址
- 其他

qemu-system-aarch64 -m 8g -smp 2 -cpu cortex-a72 -machine virt,virtualization=on,gic-version=2 -kernel /home/zcs/WORKSPACE/arceos_hypervisor/axvisor/axvisor_aarch64-qemu-virt-hv.bin -device virtio-blk-device,drive=disk0 -drive id=disk0,if=none,format=raw,file=disk.img -device virtio-net-device,netdev=net0 -netdev user,id=net0,hostfwd=tcp::5555-:5555,hostfwd=udp::5555-:5555 -nographic -machine virtualization=on,gic-version=2 -serial mon:stdio -serial telnet:localhost:4321,server
qemu-system-aarch64: -serial telnet:localhost:4321,server: info: QEMU waiting for connection on: disconnected:telnet:127.0.0.1:4321,server=on

启动另一个终端，然后执行 telnet localhost 4321，上一个终端将继续运行，并输出第一个虚拟机启动信息，第二个虚拟机启动信息将在当前终端输出。

注意事项

在同时启动 ArceOS 和 Linux 客户机时，若启动 axvisor 后只有一个 vm 有输出，另一个无显示，可能是 qemu 配置选项不全，需查看当前 qemu 版本，建议使用 9.2.2 版本，安装过程如下

# 安装编译所需的依赖包
sudo apt install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev \
              gawk build-essential bison flex texinfo gperf libtool patchutils bc \
              zlib1g-dev libexpat-dev pkg-config  libglib2.0-dev libpixman-1-dev libsdl2-dev \
              git tmux python3 python3-pip ninja-build
# 下载源码
wget https://download.qemu.org/qemu-9.2.2.tar.xz  
# 解压
tar xvJf qemu-9.2.2.tar.xz
cd qemu-9.2.2
# 生成设置文件
./configure --enable-kvm --enable-slirp --enable-debug --target-list=aarch64-softmmu,x86_64-softmmu
# 编译
make -j$(nproc)

之后编辑 ~/.bashrc 文件，在文件的末尾加入几行：

export PATH=/path/to/qemu-9.2.2/build:$PATH

最后，执行 source ~/.bashrc 更新当前 shell 即可

已知问题

ArceOS 从内存中加载启动时，如果没有 disk.img 将报错
