如何解决/消除警告：
该主机上没有 VM 客户机运行过时的虚拟机管理程序 (qemu) 二进制文件。
答案1
该输出来自被调用的程序，needrestart并且仅仅是一个信息，因为“没有 VM 客户机在此主机上运行过时的虚拟机管理程序（qemu）二进制文件”基本上翻译为“全部是最新的”。
返回“无法检查处理器微码升级”的检查无法检查您的 CPU 的微码。可以通过创建一个新的 conf 文件来跳过此操作，该文件的/etc/needrestart/conf.d/内容如下$nrconf{ucodehints} = 0;
如果您想要彻底清除消息，则可以卸载该包needrestart。但是，在更新依赖项后，进程将不会自动重新启动。
