答案1

这将是一个多部分的答案，因为至少有两个错误需要注意。为了修复第二个错误，我们需要从修复第一个错误中收集的信息。我随后将编辑此答案以提供进一步的修复。

我们在日志中看到这一点：

ixgbe 0000:0a:00.1：加载失败，因为检测到不受支持的 SFP+ 或 QSFP 模块类型。

让我们看看驱动程序参数是否有帮助。从终端：

sudo -i
echo "options ixgbe allow_unsupported_sfp=1"  >  /etc/modprobe.d/ixgbe.conf
exit

重新启动并显示：

ip addr show

我们希望现在看到第二个界面出现。

答案2

我发现这个解决方案适合我的情况。我使用的是带有英特尔 x520 2 10G SFP+/2 1GBE NIC 的 Dell R730 机箱。

eno1安装 Ubuntu 18.04.3 后我看不到该设备

https://route1.ph/2019/09/27/stretch-ixgbe-driver-allow-unsupported-sfp-modules-on-intel-x520-cards/

echo "options ixgbe allow_unsupported_sfp=1" > /etc/modprobe.d/ixgbe.conf
depmod -a
update-initramfs -u -k `uname -r`

我必须重新启动，因为netplan应用没有调出界面eno1。重新启动完成后，界面出现并且我已连接。
