起動時にlibvirtd（KVM）が起動しない理由

Fedora Server 36を最小限に新しくインストールしましたが、KVMのみが実行されます。

dnf group install "Headless Virtualization"サーバーをインストールして再起動します。

systemctl status libvirtdIE が実行されていないことを示します。

[root@dell-fedora-kvm ~]# systemctl status libvirtd

     Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; vendor preset: disabled)

             ○ libvirtd.socket

             https://libvirt.org

だから活性化しよう systemctl enable libvirtd

再起動しても自動的に起動しません。手動で起動すると、systemctl start libvirtdこれが表示されますstatus。これが問題がどこにあるかを知らせるかどうかはわかりません。

しかし、しばらくしてサービスが終了しました...
