使用 libvirtd 时，我在启动 debian 或 ubuntu 网络安装映像时遇到问题，我得到了菜单，但在选择安装菜单选项时只需得到这个：
加载 /install.amd/vmlinuz 失败：没有这样的文件或目录
我已经安装了 iso 并验证了 debian netinstall iso 在 install.amd 目录中有 vmlinuz 文件等。
这是我在失败时使用的域的 libvirtd xml：

上面的 xml 将在此结束：

手动执行此操作时，它可以在同一台机器上正常工作，并且可以让我进入安装过程：
qemu-system-x86_64 -vnc :0 -enable-kvm -serial stdio -curses -hda /opt/storage/VMs/myserver.qcow2 -m 2G -boot d -cdrom /var/lib/libvirt/boot/debian-11.3 .0-amd64-netinst.iso
是否可以使用 libvirtd xml 配置获取“-cdrom”标志？或任何其他建议？
