启动libvirtd报错解决办法：libvirtd: relocation error: libvir

今天从公司一个闲置电脑上装几个kvm耍耍docker，不料安装没有那么顺利，启动libvirtd有如下报错：

[root@kvmmaster lib64]# service libvirtd restart
正在关闭 libvirtd 守护进程：                               [失败]
启动 libvirtd 守护进程：libvirtd: relocation error: libvirtd: symbol dm_task_get_info_with_deferred_remove, version Base not defined in file libdevmapper.so.1.02 with link time reference
                                                           [失败]
 
百度是真解决不了问题，翻墙一下就找到了，网友提供的解决方案如下：

yum -y  upgrade device-mapper-libs

瞬间解决了。
