Ubuntu下用QEMU模拟运行OpenBMC
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 libvirtd4、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
