Ubuntu 22.04 KVM 安装

我遵循以下步骤：https://linuxhint.com/install-kvm-ubuntu-22-04/

当我将 netplan 应用到 yaml 文件时出现错误：

sudo netplan apply
Failed to reload network settings: No such file or directory

netplan 的调试得到如下结果：

netplan --debug generate

知道是什么原因导致了这个问题吗？

答案1

你能发布你的 netplan 配置文件吗？看来解析器对 yaml 很满意，但 netplan 不太满意。

此外，KVM 无需添加桥接器即可启动和运行，如果您只想使用本地 VM 进行一些测试，则不需要添加桥接器。Ubuntu 上的 KVM 安装在开箱即用，无需任何操作即可为您提供本地 NAT 网络。因此，如果您想测试安装的其余部分，可以恢复 netplan 文件并尝试一下。
