Solution：

1. 检查selinux是否关闭：

#vi /etc/selinux/config

SELINUX=disabled

#reboot

或者：

#setenforce 0  //暂时禁用

2.检查/etc/libvirt/libvirtd.conf和/etc/libvirt/qemu.conf的用户和组权限是否正确：

如：

/etc/libvirt/libvirtd.conf下：

  unix_sock_group = "cloud"

/etc/libvirt/qemu.conf下：

  user = "oneadmin"

  group = "cloud"

重启libvirt服务：

# /etc/init.d/libvirtd restart
