使用VMware虚拟机安装virt-manager unable to connect to libvirt的处理办法

RHEL7.0在安装完成virt-manager后，启动libvirtd服务进程

[root@demo Desktop]# systemctl enable libvirtd
[root@demo Desktop]# systemctl start libvirtd

在使用virt-manager命令启动虚拟机管理软件时，提示unable to connect to libvirt

Unable to connect to libvirt.

查看libvirtd的状态

此时可能是驱动程序的安装有问题，更新device-mapper包

[root@demo Desktop]# yum update device-mapper

重启libvirtd服务

[root@demo Desktop]# systemctl restart libvirtd
[root@demo Desktop]# systemctl status libvirtd

此时libvirtd服务显示为正常，没有出现报错，再次运行virt-manager，可以正常连接
