#cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core)
#rpm -qa qemu-img qemu-img-1.5.3-86.el7_1.2.x86_64
#./managesnapshot.sh Usage: managesnapshot.sh: -c <path to disk> -n <snapshot name> Usage: managesnapshot.sh: -d <path to disk> -n <snapshot name> Usage: managesnapshot.sh: -r <path to disk> -n <snapshot name> Usage: managesnapshot.sh: -b <path to disk> -n <snapshot name> -p <dest dir> -t <dest file>
对qcow2镜像操作如下:
#./managesnapshot.sh -c centos6.6.qcow2 -n clean
#./managesnapshot.sh -b centos6.6.qcow2 -n clean -p . -t clean.qcow2
#./managesnapshot.sh -r centos6.6.qcow2 -n clean
可以使用 qemu-img info xxx.qcow2 查看内部快照
#./managesnapshot.sh -d centos6.6.qcow2 -n clean
