Linux主机VMware Workstation中Linux客户机VM网络异常默认127.0.0.1，NAT/Custom配置无法生效的求助

大家好，最近碰到个VMware网络的棘手问题，想请各位帮忙看看。

昨天我的Linux客户机VM用NAT或者Custom网络配置都好好的，结果今天不知道哪出问题了——不管我选哪种网络设置，在客户机里执行ip a，输出的都只有127.0.0.1，完全不生效我选的配置。我的主机是Fedora系统，昨晚没改任何设置，只是把VM和主机一直开着，今天就突然不行了。

我感觉问题可能出在vmnet8上：系统似乎一直在尝试引用这个已经被删除的虚拟网卡，哪怕用管理员权限启动VMware也是如此，可我实在搞不懂为什么它要盯着vmnet8不放。

下面是vmware.log里的相关日志内容：

我因为用的是最新版Fedora和对应内核头文件，之前是手动安装的vmmon和vmnet模块，说不定这就是问题的根源？

我已经尝试过这些操作，但都没解决：

• 找Network Manager Editor里的“恢复默认设置”按钮，发现这是Windows专属功能，Fedora里没有
• 重新安装VMware，问题依旧

现在想请教各位，我该怎么重置VMware的网络设置，或者让NAT功能恢复正常工作呢？
