为什么 libvirtd (KVM) 没有在启动时启动

我有一个全新的 Fedora Server 36 最小安装，它将运行的只是 KVM。

安装dnf group install "Headless Virtualization"并重新启动服务器。

systemctl status libvirtd显示它没有运行； IE

[root@dell-fedora-kvm ~]# systemctl status libvirtd
○ libvirtd.service - Virtualization daemon
     Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; vendor preset: disabled)
     Active: inactive (dead)

             ○ libvirtd-admin.socket
             ○ libvirtd-ro.socket
             ○ libvirtd-tls.socket
             ○ libvirtd.socket
       Docs: man:libvirtd(8)
             https://libvirt.org

所以我尝试启用它 systemctl enable libvirtd

重启了还是没有自动启动。当我手动启动它时，systemctl start libvirtd这就是我得到的结果status。不确定这是否告诉我们问题可能出在哪里。

然而，该服务在一段时间后就死掉了......
