我正在嘗試在 Debian 11 (Bullseye) 上運行 KVM 虛擬機
- 我也在 ChromeOS 上從 crouton 運行這個，以防萬一這真的很重要，但我認為不是。
這是錯誤：無法完成安裝：“請求的操作無效：網路“預設”未啟動”

libvirt.libvirtError: Requested operation is not valid: network 'default' is not active
我嘗試了以下指南：https://askubuntu.com/questions/1036297/cant-start-kvm-guest-network-default-is-not-active 但提供的修復“sudo virsh net-start default”失敗：
sudo virsh net-start default
[sudo] password for luhgarlicbread:

- 另外：在 KVM > 編輯（上）> 連線詳細資料上按左下角的「啟動網路」按鈕也會出錯：

有什麼方法可以繞過所有網路檢查/完全停用 KVM 上的網路嗎？有什麼我可以嘗試的提示、技巧或修復方法嗎？這似乎有很多問題。
PS：我已經解決了所有其他問題。一個突出的問題是 libvirtd 不會以 systemctl 啟動（我認為是），所以我只是從終端手動啟動該進程並保留該術語。當我嘗試使用 virt-manager 在 KVM 中建立虛擬機器時，視窗會開啟。
