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 Prosunny@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 VirtualizationVirtualization: VT-xVirtualization type: full2、查看核心数，应该大于0sunny@ubuntu:~$ egrep -c '(vmx|svm)' /proc/cpuinfo43、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... DoneBuilding dependency tree Reading state information... Donebridge-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-1Use '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:~$ reboot4、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 $USER libvirtsunny@ubuntu:~$ sudo useradd -g $USER libvirt-kvmsunny@ubuntu:~$ sudo systemctl enable libvirtd.servicesunny@ubuntu:~$ sudo systemctl start libvirtd.serviceSynchronizing 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.xz2、解压sunny@ubuntu:~$ tar xvJf qemu-6.2.0.tar.xz3、在下载目录新建文件夹buildsunny@ubuntu:~$ cd qemu-6.2.0sunny@ubuntu:~$ mkdir build sunny@ubuntu:~$ cd build 4、配置sunny@ubuntu:~$ ../configure --enable-kvm --target-list=arm-softmmu5、编译sunny@ubuntu:~$ make6、安装sunny@ubuntu:~$ make install7、查看是否安装成功sunny@ubuntu:~$ qemu-system-arm --versionQEMU emulator version 6.2.0Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers5、启动OpenBMC
