用配置文件实现虚拟机的管理

!/bin/bash
if
[ "$1" = "start" ]
then
virsh start $2
virt-viewer $2
elif
[ "$1" = "stop" ]
then
virsh destroy $2
elif
[ "$1" = "install" ]
then
virt-install \
--name $2 \
--ram 1024 \
--file /var/lib/libvirt/images/$2.qcow2 \
--file-size 8 \
--location http://172.25.254.66/rhel7.2 \
--extra-args "ks=http://172.25.254.66/aa.cfg" &
elif
[ "$1" = "mksnopshot" ]
then
virsh destroy $2
virsh undefine $2
qemu-img create -f qcow2 -b /var/lib/libvirt/images/$2.qcow2  /var/lib/libvirt/images/$3.qcow2
virt-install \
--name $3 \
--ram 1024 \
