1. 用脚本来自动创建虚拟机
1. 查看vm6在哪儿
[root@localhost ~]# find / -name centos-7*
/var/lib/tftpboot/images/centos-7-x86_64
/var/lib/cobbler/config/distros.d/centos-7-x86_64.json
/var/lib/cobbler/config/profiles.d/centos-7-x86_64.json
/var/lib/cobbler/kickstarts/centos-7-x86_64.ks
/var/www/cobbler/images/centos-7-x86_64
/var/www/cobbler/ks_mirror/config/centos-7-x86_64.repo
/var/www/cobbler/ks_mirror/centos-7-x86_64
/var/www/cobbler/links/centos-7-x86_64
[root@localhost ~]# cd /var/lib/cobbler/config/
[root@localhost config]# pwd
/var/lib/cobbler/config
[root@localhost config]# ls
distros.d images.d packages.d repos.d
files.d mgmtclasses.d profiles.d systems.d
[root@localhost config]# ls systems.d/
vm6.json
2. 生成一台新虚拟机，获取MAC地址
3. 写脚本
[root@localhost ~]# mkdir /scripts
[root@localhost ~]# cd /scripts/
[root@localhost scripts]# ls
[root@localhost systems.d]# cat vm6.json 查看vm6，将这些内容复制到脚本里
