本文介绍通过虚拟磁盘恢复虚拟机
1 复制虚拟机配置文件
# virsh dumpxml CentOs6.8 > /etc/libvirt/qemu/centos6.8.xml
注意修改这几处
<uuid>0bdb3319-450d-9756-7254-bb12cf899dcb</uuid><driver name='qemu' type='qcow2' cache='none'/>
<source file='/data/kvm/CentOs6.8.img'/>
2 添加虚拟机定义
# virsh define /etc/libvirt/qemu/centos6.8.xml
# virsh list --all
Id Name State
----------------------------------------------------
15 CentOs6.7 running
16 centos6.8 running
- CentOs6.8 shut off
3 启动虚拟机
# virsh start centos6.8
