自从将唯一具有多个网络适配器的 Linux VM 升级到 Debian 11 以来，它的第二个适配器一直无法执行任何操作。
配置相当简单：两个 VMWare 网络适配器，每个都使用模拟的 E1000E。尝试一个简单的；
ping 10.0.26.5
10.0.26.201VM 上的 IP在哪里，以及10.0.26.5主机的 IP 在哪里，失败了。检查dmesg发现问题是一个复杂的底层问题：

大约每 2 秒重复一次。虽然这是两个相同的软件模拟 e1000e 卡，但这种情况只适用于ens34，不适用于 。ens32重新启动、网络重置或更改卡配置的各个方面（例如将速度设置为 100 Mbit）、禁用各种卸载功能或在 VMware 中重新创建卡后，问题仍然存在。以前从未见过这样的情况，完全相同的驱动程序对一张卡完美运行，而对另一张卡却无法执行任何操作。
大多数谷歌搜索似乎都会出现与该芯片的实际物理版本有关的旧问题，这些问题很久以前就已解决。
事实上，所有模拟都排除了实际的硬件问题（除此之外，ens34 恰好映射到我远程访问 VMWare 的同一端口，而且我仍然可以连接）。
将调试级别设置得稍微高一点会给出非常详细的转储；简明扼要；

答案1
从那时起，我设法通过实施以下虽然不令人满意的“Microsoft 解决方案”来解决此问题。
- 关闭虚拟机。
- 从该虚拟机中移除有问题的网络适配器。
- 启动虚拟机
- 再次将其关闭。
- 为虚拟机添加新的网络适配器。相同类型，相同名称。
- 启动虚拟机。
- 检查新网络适配器是否与 Linux 中的旧网络适配器同名。如果不同，请调整配置文件
/etc/network/interfaces，例如sed -i 's/ens33/ens34/g' /etc/network/interfaces
