kvm克隆
Kvm克隆:
克隆前需要关闭kvm虚拟机
[root@super67 ~]# virt-clone -o ubuntu16 -n ubuntu16-1 -f /var/lib/libvirt/images/ubuntu16-1.img
Cloning unbuntu16.raw | 107 B 00:00
Clone 'ubuntu16-1' created successfully.
查看克隆出来的配置文件:
[root@super67 ~]# ll /etc/libvirt/qemu/
total 20
drwxr-xr-x 2 root root 4096 Sep 4 10:31 autostart
drwx------ 3 root root 4096 Sep 4 13:43 networks
-rw------- 1 root root 2297 Sep 4 13:58 ubuntu16-1.xml
-rw------- 1 root root 2290 Sep 4 13:13 ubuntu16.xml
-rw------- 1 root root 2574 Sep 4 10:32 www.linux1.cn.xml
对比和原来的区别:
[root@super67 ~]# cd !$
cd /etc/libvirt/qemu/
[root@super67 qemu]# diff ubuntu16.xml ubuntu16-1.xml

如果克隆出现的虚拟机需要连接网络:
需要进入克隆出来的kvm虚拟机的系统中:
删除/etc/udev/…70-net……文件
修改网卡ifcfg-eth0配置
重启kvm虚拟机。
