我有一台虚拟机,它是使用以下设置在主机上创建的:http://pastebin.com/raw.php?i=sevF5V7Z
几个月来,它一直运行顺利,但最近虚拟机与外界失去了联系。发生这种情况时,登录了以下内容/var/log/messages
:

此后每 8 分钟记录一次以下内容:

虚拟机无法从外部访问(甚至无法 ping 通),因此我不得不从主机重新启动它。但所有其他服务仍在运行。
在这几个月中,仅有的另外一次eth0: Reset adapter
日志记录发生在最后 3 天的随机时段。在这 3 次事件中,网络均未中断,因为“重置适配器”似乎已成功完成:

在这 3 次成功重置之前,我收到了看门狗警告:http://pastebin.com/raw.php?i=Q1vXE5mn

我在日志中找不到与此问题相关的任何其他内容。知道为什么会发生这种情况吗?我下一步应该查看哪里?
答案1
今天早上升级到 4.3.22 后出现了类似的问题。快速解决方法是关闭我的虚拟机并将网络适配器类型更改为非英特尔类型。
已运行几个小时,没有任何问题。
