ACRN 实战应用：在一台电脑上同时安装Windows10、Ubuntu22.04、Ubuntu PREEMPT_RT实时系统并流畅运行

|--------------|---------|----|------|----------------------|
| 系统 | CPU 核心数 | 内存 | 储存 | 硬件 |
| Windows10 | 8核心 | 6G | 100G | USB、集成显卡 |
| Ubuntu 22.04 | 8核心 | 4G | 30G | NVIDIA 1050ti 显卡 |
| PREEMPT_RT | 4核心 | 4G | 20G | Intel I211(ethcat应用) |

二、配置应用场景

使用资源共享场景安装Windows10 、ubuntu22.04 、PREEMPT_RT 三系统。，

1.创建场景

1个service VM，3个post-launch VM ,如下图

点击OK 后，如下图方式显示service vm及3个Post-Lanched

2.配置VM0

如下图kernel command-line后面添加 i915.modeset=0（集成显卡留给Windows10 使用）

3.配置Windows VM1

OS type 选择Windows OS ，Memory size设置6144（6G）

CPU 设置8核心 0~7

PCI devices 添加 USB controller 及 UHD graphics (集成显卡)

Virtio network device 设置wnd_lan (虚拟机间通讯网桥)

Virtio block device 先随便写一下，后续根据实际路径添加Windows10 镜像路径

4.配置Ubuntu VM2

OS type 选择Non-Windows OS ，Memory size设置4096（4G）

CPU 设置8核心 8~15

PCI devices 添加 GTX 1050ti (独立显卡)

Virtio network device 设置Ubuntu1_lan (虚拟机间通讯网桥)

Virtio block device 先随便写一下，后续根据实际路径添加Ubuntu22.04 镜像路径

5.配置RT_VM3

WM type 选择Real-time , OS type 选择Non-Windows OS ，Memory size设置4096（4G)

CPU 设置4核心 16~19,Real-time vCPU 4个核心全部勾选，表示CPU隔离不与其他VM 共享。

PCI devices 添加 I211网口（作为实时系统的ethcat 使用）

Virtio network device 设置Ubuntu2_lan (虚拟机间通讯网桥)

Virtio block device 先随便写一下，后续根据实际路径添加RTVM 镜像路径

点击Advanced Parameters 勾选LAPIC passthrough 及I/O completion polling

设置完成后保存即可退出

6.编译acrn 内核

编译完成后把文件拷贝到工控机安装（编译细节请参考文章前面的链接）

安装后开机选择acrn-service-vm(ACRN3.2)启动，开机后显示屏不会其他显示信息，需要通过ssh 登录到service vm 再运行其他user vm 的开机脚本。

7.修改开机脚本

重启系统先选择Ubuntu 进入系统，进行启动脚本修改。

新建一个acrn-work目录
将launch_user_vm_id1.sh（Windows启动脚本）、launch_user_vm_id2.sh（Ubuntu22.04启动脚本）、launch_user_vm_id2.sh（PREEMPT_RT启动脚本）拷贝到acrn-work目录中。
由于Windows10 系统，ubuntu 22.04系统，PREEMPT_RT系统做好一次后是可以拷贝到其他机器直接使用的，本人已经做好系统img 文件，直接下载好解压会得到win10-lts.img（Windows系统文件）、rt_vm.img（PREEMPT_RT系统文件）、ubuntu_ecivm.img（Ubuntu22.04系统文件）三个系统文件，将3个系统文件拷贝到acrn-work目录中。

修改launch_user_vm_id1.sh脚本，找到以下位置，修改OVMF.fd及win10-lts.img文件路径

bash 复制代码

dm_params=(
    --windows

     -s 6,ahci,cd:/home/acrn/acrn-work/windows/winvirtio.iso
     `add_virtual_device                       5 virtio-blk /home/acrn-work/win10-ltsc.img`
   # `add_passthrough_device                   8 0000:01:00.0`
   # `add_passthrough_device                   7 0000:01:00.1`
    windows_VM1
)

修改launch_user_vm_id12.sh脚本,找到以下位置修改ubuntu_ecivm.img文件路径

bash 复制代码

dm_params=(
    `add_cpus                                 1 3 5 7 9 11 16 18`

    `add_passthrough_device                   2 0000:01:00.0`
    `add_passthrough_device                   5 0000:01:00.1`

   # `add_passthrough_device                   6 0000:00:14.0 d3hot_reset`
    ubuntu_VM2
)

修改launch_user_vm_id13.sh脚本,找到以下位置修改rt_vm.img文件路径

bash 复制代码

dm_params=(
    `add_cpus                                 13 15 17 19`
    -m 4096M
    --ovmf /usr/share/acrn/bios/OVMF.fd
    `add_virtual_device                       0:0 hostbridge`
    --virtio_poll 1000000
    `add_virtual_device                       3 virtio-net tap=ubuntu2_lan,mac_seed=${mac:0:17}-RT_VM3`
    `add_virtual_device                       4 virtio-blk /home/acrn-work/rt_vm.img`
    `add_passthrough_device                   5 0000:02:00.0`
    `add_interrupt_storm_monitor              10000 10 1 100`
    --rtvm
    --lapic_pt
    `add_logger_settings                      console=4 kmsg=3 disk=5`
    RT_VM3
)

在acrn-work 目录新建一个autorun.sh 文件，写入以下内容，用于启动3个VM 的脚本，并设置好网桥

bash 复制代码

#!/bin/bash
/home/acrn/acrn-work/launch_user_vm_id1.sh &
/home/acrn/acrn-work/launch_user_vm_id2.sh &
/home/acrn/acrn-work/launch_user_vm_id3.sh  &
sleep 20
sudo brctl addif br0 ubuntu1_lan
sudo brctl addif br0 ubuntu2_lan
sudo brctl addif br0 wind_lan
sudo ip link set dev ubuntu1_lan up
sudo ip link set dev ubuntu2_lan up
sudo ip link set dev wind_lan up

设置网桥

bash 复制代码

$ sudo apt update
$ sudo apt install bridge-utils net-tools -y
$ sudo gedit  /etc/netplan/01-network-manager-all.yaml

输入以下内容，本人设置enp2s0的物理网口作为网桥外部联网网口，不同机器可根据实际网口名称修改

bash 复制代码

network:
  version: 2
  renderer: networkd
  ethernets:
    enp2s0:  # 物理网卡名称（通过 ip a 命令查看）
      dhcp4: no
      optional: true
  bridges:
    br0:     # 网桥名称
      interfaces: [enp2s0]  # 绑定的物理网卡
      dhcp4: yes           # 启用DHCP
      parameters:
        stp: false         # 关闭生成树协议（可选）
        forward-delay: 0    # 转发延迟（可选）

bash 复制代码

sudo netplan apply

到此完成启动脚本修改工作。

三、同时启动三个系统测试

重启系统选择acrn-service-vm(ACRN3.2)启动

出现此画面时，其他电脑通过ssh 的方式登录到service VM(配置网桥的网口需联网，可以通过路由器查找service VM的IP)

本人测试service VM 登录用户是acrn ,IP是192.168.101.245（根据实际情况修改），登录成功如下图

bash 复制代码

C:\Users\hank>ssh acrn@192.168.101.245
acrn@192.168.101.245's password:

启动后，Windows10 系统会在集成显卡的显示接口输出，ubuntu22.04 会在独立显卡的显示接口输出，PREEMPT_RT实时系统无输出，需通过ssh方式登录

以下是三个系统的硬件信息与资源分配方式一致

Windows 10 系统 8核心，内存6GB

Ubuntu22.04系统 8核心，内存4GB

PREEMPT_RT实时系统 4核心，内存4GB

四、实时性测试

我们在Windows10 系统下通过实时SSH 方式登录到PREEMPT_RT实时系统，在实时系统中运行cyclictest软件测试系统抖动，同时Windows10 系统CPU 满足跑，验证是否干扰PREEMPT_RT系统是实时性

Windows10 SSH 方式登录到PREEMPT_RT系统,本次测试PREEMPT_RT系统IP为：192.168.101.246，账号root，密码root

bash 复制代码

C:\Users\hank>ssh root@192.168.101.246
root@192.168.101.246's password:
Last login: Thu Dec  4 13:45:49 2025 from 192.168.101.240
root@vc-vcp2100-rpv7:~#

测试条件：

1、一台工控机同时运行Windows10、Ubuntu22.04、Ubuntu PREEMPT_RT三个系统。

2、Windows10 系统 8核心100%满载运行。

3、Ubuntu PREEMPT_RT跑codesys runtime 运行PCL 程序，通过ethercat 控制远程IO 每隔1毫秒开关一次外部IO，如下图。

测试结果：

在工控如此极致运行条件下，PREEMPT_RT系统仍能保持良好的抖动性。

总结

ACRN 共享模式下，能在一台电脑上同时运行Windows10、Ubuntu22.04、Ubuntu PREEMPT_RT实时系统，并且在流畅运行同时也确保系统之间互不干预。
