我正在尝试在 Debian 11 (Bullseye) 上运行 KVM 虚拟机
- 我也在 ChromeOS 上从 crouton 运行这个，以防万一这真的很重要，但我认为不是。
这是错误：无法完成安装：“请求的操作无效：网络‘默认’未激活”

我尝试了以下指南：https://askubuntu.com/questions/1036297/cant-start-kvm-guest-network-default-is-not-active 但提供的修复“sudo virsh net-start default”失败：
sudo virsh net-start default

- 另外：在 KVM > 编辑（顶部）> 连接详细信息上按左下角的“启动网络”按钮也会出错：

有什么方法可以绕过所有网络检查/完全禁用 KVM 上的网络吗？有什么我可以尝试的提示、技巧或修复方法吗？这似乎有很多问题。
PS：我已经解决了所有其他问题。一个突出的问题是 libvirtd 不会以 systemctl 启动（我认为是），所以我只是从终端手动启动该过程并保留该术语。当我尝试使用 virt-manager 在 KVM 中创建虚拟机时，窗口打开。
