不登录虚拟机创建虚拟机

运行脚本名 你创建虚拟机名字

切记 配置的IP 是192.168.4.0 网段的 , 如需要改的时候可以参照以下脚本
#!/bin/bash
#This script will create a virsh-domain named $1.
IMG_DIR=/var/lib/libvirt/images
UUID=uuidgen

#定义域

virdef () {
cp $IMG_DIR/.rhel7.xml /tmp/$1.xml

sed -i "/<uuid>/s#<uuid>.*<\/uuid>#<uuid>$UUID<\/uuid>#" /root/vxml/$1.xml

sed -i "/<name>/s/rh7_template/$1/" /tmp/$1.xml
sed -i "/rh7_template\.img/s/rh7_template/$1/" /tmp/$1.xml
virsh define /tmp/$1.xml >/dev/null
echo -e "create $1 \e[32;1m[OK]\e[0m"

}

#通过qemu-img创建虚拟机叠加镜像，记录改动，不对原始镜像进行修改；
#vircre () {

qemu-img create -f qcow2 -b $IMG_DIR/.rh7_template.qcow2 $IMG_DIR/$1 >/dev/null

#}

#克隆镜像
vircre () {
qemu-img create -f qcow2 -b $IMG_DIR/.rh7_template.img $IMG_DIR/$1 >/dev/null
}

#创建域

vircre $1.img
virdef $1
