js9905com金沙网站CentOS 7 virt-manager 无法连接本地的

Linux操作系统 : CentOS 7 Gnome Desktop

问题描述:

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 可以查看到kvm-intel模块已经加入至内核中。

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

重启libvirtd服务,查看日志记录/var/log/messages
