根据最初的实验计划，新手小白继续尝试，本篇内容，为大家分享在openEuler中安装虚拟机。
本篇内容主要包含的内容如下：
01、启动libvirtd服务并设置开机自启；
02、创建存储池；
03、创建虚拟机磁盘空间；
04、创建虚拟机；
05、虚拟机的一些操作和命令；
06、登陆虚拟机系统。
参考文献如下：
https://www.hikunpeng.com/document/detail/zh/kunpengcpfs/ecosystemEnable/QEMU-KVM/kunpengkvm_03_0010.html
下面开始具体内容：
01、启动libvirtd服务并设置开机自启。
systemctl start libvirtd
systemctl enable libvirtd
启动libvirtd服务
在Linux系统中，libvirtd是管理虚拟化技术的一个关键组件，通常包括对KVM、QEMU等虚拟化技术的支持。

02、创建存储池。
a、创建存储池目录，配置目录权限。
mkdir -p /home/kvm/images
chown root:root /home/kvm/images
chmod 755 /home/kvm/images
b、定义一个存储池并绑定目录，建立基于文件夹的存储池、激活、设置开机启动。
virsh pool-define-as StoragePool --type dir --target /home/kvm/images
virsh pool-build StoragePool
virsh pool-start StoragePool
virsh pool-autostart StoragePool
c、查看存储池信息。
virsh pool-info StoragePool
virsh pool-list
[root@PengFei ~]# mkdir -p /home/kvm/images
[root@PengFei ~]# cd /home/kvm/images
[root@PengFei images]# pwd
/home/kvm/images
[root@PengFei images]# chown root:root /home/kvm/images
[root@PengFei images]# chmod 755 /home/kvm/images

[root@PengFei images]# virsh pool-list

[root@PengFei images]#
03、创建虚拟机磁盘空间。
a、创建卷。
创建名称为1.img的卷，所在存储池为StoragePool。
硬盘文件的格式必须为qcow2格式。
[root@PengFei ~]# virsh vol-create-as --pool StoragePool --name 1.img --capacity 20G --allocation 1G --format qcow2
Vol 1.img created
上述命令中创建的卷容量为20G，初始分配1G，文件格式类型为qcow2。具体可根据需要修改卷的大小和配置。
b、查看卷信息。
[root@PengFei ~]# virsh vol-info /home/kvm/images/1.img
Name: 1.img
Type: file
Capacity: 20.00 GiB
Allocation: 196.00 KiB
[root@PengFei ~]#
04、创建虚拟机。
a、准备iso文件
[root@PengFei download]# ll

b、创建一个名为vm1的虚拟机，刚才已经将openEuler-24.03-LTS-SP1-aarch64-dvd.iso文件下载到“/download”路径下（非“/root”路径即可），执行如下命令开始创建虚拟机。
[root@PengFei download]# virt-install --name=vm1 --vcpus=4 --ram=8192 --disk path=/home/kvm/images/1.img,format=qcow2,size=20,bus=virtio --location /download/openEuler-24.03-LTS-SP1-aarch64-dvd.iso --network network=default --nographics
上述命令中为虚拟机分配了4个vCPU、8G内存，使用1.img作为系统卷。可根据实际需要修改虚拟机的规格和配置。
执行完成上述命令后，需要等待一段时间，随后将进入安装虚拟机的操作系统环节。

c、在安装虚拟机的操作系统环节中：
配置状态显示为“Processing...”的配置项表示正在进行自动配置。输入“r”回车后可以刷新当前状态。
自动配置结束后，针对所有带有“!”的选项，需要先输入选项对应的序号，再按回车，然后根据提示进行手动配置。
中间不小心中断，退出来了，到了这个界面。
感觉是没有装好系统的样子，但是进了虚拟机，有一个操作提示，也是有一个小的系统，于是乎，退出来，将image删除，将虚拟机关闭删除。
重新进行“b、创建一个名为vm1的虚拟机，刚才已经将openEuler-24.03-LTS-SP1-aarch64-dvd.iso文件下载到“/download”路径下（非“/root”路径即可），执行如下命令开始创建虚拟机。”主要是设置root的密码，还有 Installation Destination
d、按照指示完成所有配置后，输入“b”回车后开始安装。
e、系统安装完成后，登录系统。

通过实验，对虚拟机的配置和使用有了一定的了解，但具体在实际过程中怎么使用，包括IP地址怎么去配置，怎么配置网络信息和网卡，怎么部署应用，等等一系列问题，zai比如怎么通过xshell工具来直接远程登录到虚拟机内部，还要继续学习。这篇先写到这里，继续加油。

'%3e%3c/path%3e%3c/g%3e%3c/g%3e%3c/svg%3e)
根据最初的实验计划，新手小白继续尝试，本篇内容，为大家分享在openEuler中安装虚拟机。
本篇内容主要包含的内容如下：
01、启动libvirtd服务并设置开机自启；
02、创建存储池；
03、创建虚拟机磁盘空间；
04、创建虚拟机；
05、虚拟机的一些操作和命令；
06、登陆虚拟机系统。
参考文献如下：
https://www.hikunpeng.com/document/detail/zh/kunpengcpfs/ecosystemEnable/QEMU-KVM/kunpengkvm_03_0010.html
下面开始具体内容：
01、启动libvirtd服务并设置开机自启。
systemctl start libvirtd
systemctl enable libvirtd
启动libvirtd服务
在Linux系统中，libvirtd是管理虚拟化技术的一个关键组件，通常包括对KVM、QEMU等虚拟化技术的支持。

02、创建存储池。
a、创建存储池目录，配置目录权限。
mkdir -p /home/kvm/images
chown root:root /home/kvm/images
chmod 755 /home/kvm/images
b、定义一个存储池并绑定目录，建立基于文件夹的存储池、激活、设置开机启动。
virsh pool-define-as StoragePool --type dir --target /home/kvm/images
virsh pool-build StoragePool
virsh pool-start StoragePool
virsh pool-autostart StoragePool
c、查看存储池信息。
virsh pool-info StoragePool
virsh pool-list
[root@PengFei ~]# mkdir -p /home/kvm/images
[root@PengFei ~]# cd /home/kvm/images
[root@PengFei images]# pwd
/home/kvm/images
[root@PengFei images]# chown root:root /home/kvm/images

03、创建虚拟机磁盘空间。
a、创建卷。
创建名称为1.img的卷，所在存储池为StoragePool。
硬盘文件的格式必须为qcow2格式。
[root@PengFei ~]# virsh vol-create-as --pool StoragePool --name 1.img --capacity 20G --allocation 1G --format qcow2
Vol 1.img created
上述命令中创建的卷容量为20G，初始分配1G，文件格式类型为qcow2。具体可根据需要修改卷的大小和配置。
b、查看卷信息。
[root@PengFei ~]# virsh vol-info /home/kvm/images/1.img
Name: 1.img
Type: file
Capacity: 20.00 GiB
Allocation: 196.00 KiB
[root@PengFei ~]#
04、创建虚拟机。
a、准备iso文件

b、创建一个名为vm1的虚拟机，刚才已经将openEuler-24.03-LTS-SP1-aarch64-dvd.iso文件下载到“/download”路径下（非“/root”路径即可），执行如下命令开始创建虚拟机。
[root@PengFei download]# virt-install --name=vm1 --vcpus=4 --ram=8192 --disk path=/home/kvm/images/1.img,format=qcow2,size=20,bus=virtio --location /download/openEuler-24.03-LTS-SP1-aarch64-dvd.iso --network network=default --nographics
上述命令中为虚拟机分配了4个vCPU、8G内存，使用1.img作为系统卷。可根据实际需要修改虚拟机的规格和配置。
执行完成上述命令后，需要等待一段时间，随后将进入安装虚拟机的操作系统环节。

c、在安装虚拟机的操作系统环节中：
配置状态显示为“Processing...”的配置项表示正在进行自动配置。输入“r”回车后可以刷新当前状态。
自动配置结束后，针对所有带有“!”的选项，需要先输入选项对应的序号，再按回车，然后根据提示进行手动配置。
中间不小心中断，退出来了，到了这个界面。
感觉是没有装好系统的样子，但是进了虚拟机，有一个操作提示，也是有一个小的系统，于是乎，退出来，将image删除，将虚拟机关闭删除。
重新进行“b、创建一个名为vm1的虚拟机，刚才已经将openEuler-24.03-LTS-SP1-aarch64-dvd.iso文件下载到“/download”路径下（非“/root”路径即可），执行如下命令开始创建虚拟机。”主要是设置root的密码，还有 Installation Destination
d、按照指示完成所有配置后，输入“b”回车后开始安装。
e、系统安装完成后，登录系统。

通过实验，对虚拟机的配置和使用有了一定的了解，但具体在实际过程中怎么使用，包括IP地址怎么去配置，怎么配置网络信息和网卡，怎么部署应用，等等一系列问题，zai比如怎么通过xshell工具来直接远程登录到虚拟机内部，还要继续学习。这篇先写到这里，继续加油。
