CentOS 7 virt-manager 無法連線原生的hypervisor

Linux作業系統 : CentOS 7 Gnome Desktop

問題描述：

CentOS 7 下使用yum install virt-manager之後，使用virt-manager無法連線原生的hypervisor。

使用lsmod 可以檢視到kvm-intel模組已經加入至核心中。

使用命令列工具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

重新啟動libvirtd服務，檢視紀錄檔記錄/var/log/messages
