找不到 libvirtd.service

Question

当我尝试使用 sudo systemctl start libvirtd 启动 libvirt 时
无法启动 libvirtd.service:未找到单元 libvirtd.service。发生。

当我尝试使用 apt list 来检测这里是 libvirt

apt 列表 | grep libvirt 结果是

引用Ubuntu documents :

# To install the necessary packages, from a terminal prompt enter:
sudo apt update
sudo apt install qemu-kvm libvirt-daemon-system

您应该检查并遵循一些必要的步骤或根据文档进行配置。
