安装好Centos虚机系统，进行标准化配置，最后安装cloud-init，如下：
yum -y install qemu-guest-agent
yum -y install cloud-init
systemctl enable cloud-init-local.service
systemctl start cloud-init-local.service
systemctl enable cloud-init.service
systemctl start cloud-init.service
systemctl enable cloud-config.service
systemctl start cloud-config.service
systemctl enable cloud-final.service
systemctl start cloud-final.service
cloud-init init --local #检查是否可用
配置完成后关机，删除硬件网卡，添加 Cloud-Init 硬件，然后转换为模板
qm set 1003 --ide2 local-lvm:cloudinit
通过模板克隆新的虚机，自动配置IP，脚本如下：
#!/bin/bash #Function:Clone 1 vm from template host='10.10.20.11' vmname='vmtest02' cpu_cores=8 memory_size=16384 ip='10.10.26.21' vlanid=26 description='description' #get vm max id pve_id_max=`qm list |awk '{print $1}' |tail -n 1` pve_vm_id=`expr $pve_id_max + 1` #get cpu cores every cpu socket cpu_cores_1=`expr $cpu_cores / 2` storage=`echo $host |awk -F .
