  • CentOS 7 virt-manager 无法连接本地的hypervisor

    OS : CentOS 7 Gnome Desktop


    问题描写叙述:

    CentOS 7 下使用yum install virt-manager之后。使用virt-manager无法连接本地的hypervisor。


    使用lsmod 能够查看到kvm-intel模块已经增加至内核中。


    使用命令行工具virsh

    [root@localhost qemu]# virsh define CCnode.xml

    error: failed to connect to the hypervisor

    error: no valid connection

    error: no connection driver available for <null>

    error: Failed to reconnect to the hypervisor


    重新启动libvirtd服务,查看日志记录/var/log/messages

    日志记录错误关键部分:

    经过Google。解决此问题仅仅需更新软件包


    查看包版本号:

    yum info device-mapper-libs          


    更新软件包:

    yum update device-mapper-libs
