Ubuntu 22.04 KVM安装

Question

我遵循这个程序：https://linuxhint.com/install-kvm-ubuntu-22-04/

当我将netplan应用于yaml文件时，我会得到一个错误：

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

调试netplan产生的结果：

netplan --debug generate

你知道是什么引起了这个问题吗？

Answer 1

你能张贴你的netplan配置文件吗？似乎解析器对yaml很满意，但netplan不太满意。

另外，KVM将在不添加桥的情况下启动和运行，如果您只希望本地VM进行一些测试，则不需要它。在ubuntu上安装KVM可以让您在不需要任何努力的情况下，立即使用本地NAT网络。因此，如果您想测试安装的其余部分，可以还原netplan文件并尝试..
