无法打开TUN/TAP / dev /as0t0:没有这样的文件或目录(errno=2)

Question

我只是尝试在使用OpenVPN的Debian上安装OpenVZ访问服务器。但是，当我尝试从管理面板启动它时，我会得到以下错误：

service failed to start or returned error status

在试图在OpenVPN上安装OpenVZ时，我也遇到了类似的问题。您有很好的信息：http://wiki.openvz.org/VPN_通过_这个_TUN/TAP_设备

你的问题可能是：

• tun模块没有加载在HW-节点上。如果你租了一个VPS，问你的VPS提供商的tun-设备。否则，按照说明如何在HW-节点安装tun-模块.
• CT对TUN/TAP设备没有权限。按照上面的说明。
