在 Ubuntu 18.04 上使用 Gnome-Boxes 时，尝试启动任何磁盘映像时始终出现错误。有人能帮我解释一下吗？
我无法从故障排除日志中得出任何结论：

我很感谢您的时间。

当我尝试时，我收到了一些更有用的消息virt-manager。使用以下命令安装：sudo apt install virt-manager
在它起作用之前我做了几件事，但并不是每件事都是必要的：
sudo apt install virt-manager
sudo systemctl enable libvirtd
sudo systemctl enable virtlogd
sudo systemctl start libvirtd
sudo systemctl start virtlogd
sudo adduser `id -un` kvm
并登录和退出以确保组添加生效。但在此之后，和都gnome-boxes设法virt-manager启动了图像。
