Ubuntu每天晚上都会下降- VM

Question

我们在Hyper上有一个Ubuntu，在它上我们安装了一个LAMP服务器，并且可以从内部网访问一个内部域。

每天我们必须重新启动它，因为到服务器的连接会下降。

当我们登录到VM时，网络被关闭了，根本没有互联网。

我看到了日志，凌晨2点发生了一些事情

以下是更多信息：

我不能评论，所以我会在这里回答。

这行udev: renamed network interface eth0 to eth2不是您日志中的问题吗？有关解析的一些示例，请参见http://blog.giuseppeurso.net/udev-renamed-network-interface-eth-to-eth/或http://tadek.pietraszek.org/blog/2008/03/04/wth-eth0-got-renamed-to-eth2-after-an-upgrade/。
