Ubuntu下用QEMU模拟运行OpenBMC

article 2025/3/31 22:32:49

1、前言

        在调试过程中，安装了很多依赖库，具体没有记录。关于kvm，也没理清具体有什么作用。本文仅记录，用QEMU成功的将OpenBMC跑起来的过程，做备忘，也供大家参考。

2、环境信息

VMware® Workstation 15 Pro

sunny@ubuntu:~$ uname -a
Linux ubuntu 5.4.0-150-generic #167~18.04.1-Ubuntu SMP Wed May 24 00:51:42 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

3、虚拟化设置

进入虚拟机：

1、查看是否支持虚拟化
   sunny@ubuntu:~$ LC_ALL=C lscpu | grep Virtualization
   Virtualization:      VT-x
   Virtualization type: full

2、查看核心数，应该大于0
   sunny@ubuntu:~$ egrep -c '(vmx|svm)' /proc/cpuinfo
   4

3、安装KVM，已经安装过
   sunny@ubuntu:~$ sudo apt install qemu qemu-kvm virt-manager bridge-utils
   [sudo] password for sunny: 
   Reading package lists... Done
   Building dependency tree       
   Reading state information... Done
   bridge-utils is already the newest version (1.5-15ubuntu1).
   qemu-kvm is already the newest version (1:2.11+dfsg-1ubuntu7.42).
   qemu is already the newest version (1:2.11+dfsg-1ubuntu7.42).
   virt-manager is already the newest version (1:1.5.1-0ubuntu1.2).
   The following packages were automatically installed and are no longer required:
     gir1.2-goa-1.0 gir1.2-snapd-1
   Use 'sudo apt autoremove' to remove them.
     0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

3、重启虚拟机
    sunny@ubuntu:~$ reboot

4、虚拟机起来后，将用户添加到适当的组中，启用并启动libvirt服务
    sunny@ubuntu:~$ sudo useradd -g $USER libvirt
    sunny@ubuntu:~$ sudo useradd -g $USER libvirt-kvm
    sunny@ubuntu:~$ sudo systemctl enable libvirtd.service
    sunny@ubuntu:~$ sudo systemctl start libvirtd.service
      Synchronizing state of libvirtd.service with SysV service script with         
      /lib/systemd/systemd-sysv-install.
      Executing: /lib/systemd/systemd-sysv-install enable libvirtd

4、安装QENU

1、下载源码
   sunny@ubuntu:~$ wget https://download.qemu.org/qemu-6.2.0.tar.xz

2、解压
   sunny@ubuntu:~$ tar xvJf qemu-6.2.0.tar.xz

3、在下载目录新建文件夹build
   sunny@ubuntu:~$ cd qemu-6.2.0
   sunny@ubuntu:~$ mkdir build 
   sunny@ubuntu:~$ cd build  

4、配置
   sunny@ubuntu:~$ ../configure --enable-kvm  --target-list=arm-softmmu

5、编译
   sunny@ubuntu:~$ make

6、安装
   sunny@ubuntu:~$ make install

7、查看是否安装成功
  sunny@ubuntu:~$ qemu-system-arm --version
    QEMU emulator version 6.2.0

5、启动OpenBMC

官方OpenBMC镜像下载：
https://jenkins.openbmc.org/job/latest-master/label=docker-builder,target=romulus/lastSuccessfulBuild/artifact/openbmc/build/tmp/deploy/images/romulus/obmc-phosphor-image-romulus.static.mtd

启动并登录：（用户名/密码：root/0penBmc ，0penBmc 首字母是零）
