我安装了该xen-hypervisor软件包，但系统冻结了，我不知道如何解决，所以我从源代码编译。它显示了相同的问题，所以我假设它与硬件有关，并（成功）切换到 KVM。
问题是，现在，尽管make uninstall 从 xen 的源目录运行，系统上似乎仍残留着许多 xen，我找不到清除它们的好资源。我不介意，但我认为这是现在导致此问题的原因（和 的输出systemctl status systemd-modules-load）journalctl _PID=3898：

/etc/modules我确实在（唯一的模块配置，由来自的符号链接引用）中查找了错误的模块加载行/etc/modules-load.d/modules.conf，但只有vhost_netKVM 的网络桥接器有该行。
编辑：我已经停止了错误（通过删除/usr/local/lib/modules-load.d/xen.conf并重新启动服务），但尚未清除。发现此文件列表在安装时被修改，但无法识别所有文件。
关于是否可以安全删除其中任何一个，您有什么想法吗？

您可以使用以下命令删除该包。
apt-get 删除 xen-hypervisor-amd64 / apt-get 删除 centos-release-xen
或者
apt-get purge xen-hypervisor-amd64 / apt-get purge centos-release-xen
