我通常在专用服务器上安装模板虚拟机，然后将磁盘复制到其他生产服务器。这种方法已经使用多年，并且至今仍然有效，除了一种情况外。
我已经在上创建了一个虚拟域debian-8.1 / libvirt-1.2.9-9 / qemu-1:2.1+dfsg-12+deb8u1 / virtinst-1:1.0.1-5并用 安装了它debian-9.5。
如果我将磁盘复制到debian-8.6 / libvirt-1.2.9-9+deb8u3 / qemu-1:2.1+dfsg-12+deb8u7 / virtinst-1:1.0.1-5并启动它，那么我在 vnc 控制台上看到的内容如下：

我不知道这是什么意思，也无法在 Google 上找到任何相关的信息。
有谁知道可能出了什么问题？

我已经在各种虚拟化主机上测试了同一个磁盘。除了一个系统外，它在其他地方都可以正常工作：
