UNetLab 启动不了设备
UNetLab按教程安装完后启动不了设备。试了4次，修改几次操作错误后，点击start有提示启动失败:Failed to start node (12) 求解？？
镜像不对，或者没有执行权限修正命令 我研究了一下 有 3 个方面的问题1.查看nano /etc/hosts
127.0.0.1 localhost
“unl的ip” unl01.example.com unl01
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
127.0.0.127 xml.cisco.com
2权限修复
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
3。iol 许可
