楼主新手,给服务器装kvm,在装virt-manager virt-viewer时报错,如下:
Transaction check error:
file /usr/lib/systemd/system/blk-availability.service from install of device-mapper-7:1.02.107-5.el7_2.1.x86_64 conflicts with file from package lvm2-7:2.02.105-14.el7.x86_64

,突然看到一篇日志说运行这个命令可解:
yum install libdevmapper* -y
于是就试了,确实解决报错问题并安装成功了![](https://gsp0.baidu.com/5aAHeD3nKhI2p27j8IqW0jdnxx1xbK/tb/editor/images/client/image_emoticon7.png)
于是问题就来了。。。
锁屏再登录时,界面狂闪,不能选其他用户,密码只能输入一位,一直有验证错误的提示,可远程没有问题,于是重启!可重启后一到登录界面就黑了,嘛都不显示了,这时远程还是可以登录。

,突然看到一篇日志说可能bios中虚拟技术没打开,虽然觉得很扯。。。试一试总是好的。。。。。。结果bios中没找到此选项
,不过cpu肯定是支持,可能默认了吧、、、于是重启!
好吧,到此为止了,centos7的7画面过后,就啥都显示不出来了,机器需要认证上网,也没法远程了![](https://gsp0.baidu.com/5aAHeD3nKhI2p27j8IqW0jdnxx1xbK/tb/editor/images/client/image_emoticon12.png)
求各位大大来排忧解惑![](https://gsp0.baidu.com/5aAHeD3nKhI2p27j8IqW0jdnxx1xbK/tb/editor/images/client/image_emoticon24.png)
