OS : 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
