一、基础准备工作

（1）下载ARM架构的openEuler操作系统镜像

mkdir -p /opt/os
cd /opt/os
wget https://repo.openeuler.org/openEuler-22.03-LTS/ISO/aarch64/openEuler-22.03-LTS-aarch64-dvd.iso --no-check-certificate
chmod 777 /opt/os/openEuler-22.03-LTS-aarch64-dvd.iso

（3）下载ARM架构的EFI
路径为 /usr/share/AAVMF/AAVMF_CODE.fd

yum install -y http://mirror.centos.org/altarch/7/os/aarch64/Packages/AAVMF-20180508-6.gitee3198e672e2.el7.noarch.rpm

（4）安装基础依赖

yum install -y kvm qemu virt-viewer virt-manager libvirt libvirt-python python-virtinst
yum install libguestfs-tools -y
yum install virt-install.noarch -y
systemctl enable libvirtd
systemctl start libvirtd
usermod -aG libvirt $(whoami)
yum install virt-install virt-viewer virt-manager -y

（5）修改配置文件
将如下两行放开注释

vi /etc/libvirt/qemu.conf

然后搜索 nvram，并将如下几行放开注释

然后重启

reboot

（6）下载qemu

cd /opt
wget https://download.qemu.org/qemu-4.2.0.tar.xz

（7）安装基础依赖

yum install zlib-devel glib2-devel pixman-devel gcc -y

（8）解压qemu

cd /opt/
tar xf qemu-4.2.0.tar.xz

（9）安装qemu

cd qemu-4.2.0/
./configure --target-list=aarch64-softmmu --prefix=/usr
make -j8
make install

二、自动创建基于dhcp自动获取ip地址的openEuler虚拟机

（1）创建磁盘

rm -rf /var/lib/libvirt/images/test.qcow2
systemctl restart libvirtd
qemu-img create -f qcow2 /var/lib/libvirt/images/test.qcow2 30G

（2）创建ks文件

rm -rf /opt/openEuler/dhcp/ks.cfg
mkdir -p /opt/openEuler/dhcp/
vi /opt/openEuler/dhcp/ks.cfg

ks文件内容如下：

#version=DEVEL
# System authorization information
auth --enableshadow --passalgo=sha512
# Use CDROM installation media
cdrom
# Use graphical install
text
# Run the Setup Agent on first boot
firstboot --enable
ignoredisk --only-use=sda
# Keyboard layouts
keyboard --vckeymap=cn --xlayouts='cn'
# System language
lang zh_CN.UTF-8
# Network information

network  --hostname=test
# Root password

# System services

# System timezone

# System bootloader configuration
bootloader --append=" crashkernel=auto" --location=mbr --boot-drive=sda
# Partition clearing information

# Disk partitioning information
part /boot --fstype="xfs" --ondisk=sda --size=1024
part /boot/efi --fstype="efi" --ondisk=sda --size=600 --fsoptions="umask=0077,shortname=winnt"
part pv.252 --fstype="lvmpv" --ondisk=sda --size=18050
volgroup centos --pesize=4096 pv.252
logvol swap  --fstype="swap" --size=2048 --name=swap --vgname=centos
logvol /  --fstype="xfs" --size=16000 --name=root --vgname=centos
%packages
@^minimal-environment
@standard
@core
chrony
kexec-tools
%end
reboot
%anaconda
pwpolicy root --minlen=6 --minquality=1 --notstrict --nochanges --notempty
pwpolicy user --minlen=6 --minquality=1 --notstrict --nochanges --emptyok
pwpolicy luks --minlen=6 --minquality=1 --notstrict --nochanges --notempty
%end

（3）通过virt-install启动虚拟机

virt-install\--name test\--memory 2048\--vcpus=1\--os-type linux\--location /opt/os/openEuler-22.03-LTS-aarch64-dvd.iso \--disk path=/var/lib/libvirt/images/test.qcow2,size=20,format=qcow2  \--graphics=none \--console pty,target_type=serial \--initrd-inject ks.cfg --extra-args "inst.ks=file:/ks.cfg console=ttyS0,115200n8"

三、自动创建配置静态IP地址的openEuler虚拟

（1）创建磁盘，在创建之前如果已经存在则先删除

rm -rf /var/lib/libvirt/images/test.qcow2
qemu-img create -f qcow2 /var/lib/libvirt/images/test.qcow2 30G

（2）创建ks.cfg文件

rm -rf /opt/openEuler/static/ks.cfg
mkdir -p /opt/openEuler/static/
vi /opt/openEuler/static/ks.cfg

然后向ks.cfg中写入如下内容

#version=DEVEL
# System authorization information
auth --enableshadow --passalgo=sha512
# Use CDROM installation media
cdrom
# Use graphical install
text
# Run the Setup Agent on first boot
firstboot --enable
ignoredisk --only-use=sda
# Keyboard layouts
keyboard --vckeymap=cn --xlayouts='cn'
# System language
lang zh_CN.UTF-8# Network information
network  --bootproto=static --device=ens3 --gateway=192.168.1.1 --ip=192.168.1.100 --nameserver=8.8.8.8 --netmask=255.255.255.0
network  --hostname=test# Root password
rootpw --iscrypted $6$iqWsh8SEbDTI2rvb$ri6nTjR79jQ9MDrzcKGkEhy6k8TQg2jV3P8JJ4E.WNaIfL1kFSUlIWBtA5bDjCajH213TKUeBQT6SaYbtnKzN/
# System services
services --enabled="chronyd"
# System timezone
timezone Asia/Shanghai --isUtc
# System bootloader configuration
bootloader --append=" crashkernel=auto" --location=mbr --boot-drive=sda
# Partition clearing information
clearpart --none --initlabel
# Disk partitioning information
part /boot --fstype="xfs" --ondisk=sda --size=1024
part /boot/efi --fstype="efi" --ondisk=sda --size=600 --fsoptions="umask=0077,shortname=winnt"
part pv.252 --fstype="lvmpv" --ondisk=sda --size=19455
volgroup centos --pesize=4096 pv.252
logvol swap  --fstype="swap" --size=2048 --name=swap --vgname=centos
logvol /  --fstype="xfs" --size=17404 --name=root --vgname=centos%packages
@^minimal-environment
@standard
@core
chrony
kexec-tools%end
reboot%anaconda
pwpolicy root --minlen=6 --minquality=1 --notstrict --nochanges --notempty
pwpolicy user --minlen=6 --minquality=1 --notstrict --nochanges --emptyok
pwpolicy luks --minlen=6 --minquality=1 --notstrict --nochanges --notempty
%end

（3）然后通过virt-install命令启动虚拟机

virt-install \--name test \--memory=1024 \--vcpus=1 \--os-type linux \--location /opt/os/openEuler-22.03-LTS-x86_64-dvd.iso \--disk path=/var/lib/libvirt/images/test.qcow2,size=20,format=qcow2  \--graphics=none \--console pty,target_type=serial \--initrd-inject ks.cfg --extra-args "inst.ks=file:/ks.cfg console=ttyS0,115200n8"

（4）比如这里配置了创建的虚拟机的ip地址为192.168.1.100，则虚拟机创建完成后，不需要登录查看ip，直接使用ip进行ping或者ssh均是可以的。
