qemu工具搭建aarch64系统

下载准备

• 下载qemu: https://qemu.weilnetz.de/w64/2022/qemu-w64-setup-20220831.exe

• 下载固件：https://publishing-ie-linaro-org.s3.amazonaws.com/releases/components/kernel/uefi-linaro/16.02/release/qemu64/QEMU_EFI.fd?Signature=lueMJ1QvyHn%2FcKm%2BG6IQF56e%2Bs8%3D&Expires=1733195413&AWSAccessKeyId=AKIAIELXV2RYNAHFUP7A

• 使用的openEuler欧拉系统，下载镜像后进行解压：https://repo.openeuler.org/openEuler-20.03-LTS/virtual_machine_img/aarch64/openEuler-20.03-LTS.aarch64.qcow2.xz

构建

• 打开win10 下powershell，构建img

  qemu-img create -f qcow2 openeuler.img 80G
  

• 构建系统，hostfwd=tcp::8081-:22很重要，用于ssh可以访问qemu内的系统，否则无法传输文件和远程访问操作，系统内22映射到外部8081端口(可以自行更改)

  qemu-system-aarch64 -m 4096 -cpu cortex-a57 -smp 4 -M virt -net user,hostfwd=tcp::8081-:22 -net nic,model=virtio -bios D:\soft\qemu\arm\QEMU_EFI.fd -hda D:\Users\Downloads\openEuler-20.03-LTS.aarch64.qcow2\openEuler-20.03-LTS.aarch64.qcow2
  

• 会弹出界面，按ctrl+alt+2后进行安装，之后输入用户名：root，密码：openEuler12#$

系统一些准备

• 安装之后不能上外网，发现没有ifcfg-eth0文件，可以手动创建后重启

  cd /etc/sysconfig/network-scripts/
  [root@localhost network-scripts]# cat ifcfg-eth0
  TYPE=Ethernet
  PROXY_METHOD=none
  BROWSER_ONLY=no
  BOOTPROTO=dhcp
  DEFROUTE=yes
  IPV4_FAILURE_FATAL=no
  IPV6INIT=yes
  IPV6_AUTOCONF=yes
  IPV6_DEFROUTE=yes
  IPV6_FAILURE_FATAL=no
  NAME=eth0
  DEVICE=eth0
  ONBOOT=yes
  

• service NetworkManager restart，ifconfig后发现有对应ip了

  eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500inet 10.0.2.15  netmask 255.255.255.0  broadcast 10.0.2.255
  

• yum源，可以install包

  cd /etc/yum.repos.d
  vi openEuler_aarch64.repo[base]
  name=base
  baseurl=https://repo.openeuler.org/openEuler-20.03-LTS/OS/aarch64/
  enabled=1
  gpgcheck=0
  

  • 执行

    yum clean all
    yum makecache
