Как мне полностью удалить Xen или хотя бы остановить эти ошибки?

Я установил xen-hypervisorпакет, но это заморозило мою систему, и я не знал, как ее решить, поэтому скомпилировал из исходного кода. Это показывало ту же проблему, поэтому я предположил, что это связано с аппаратным обеспечением, и переключился (успешно) на KVM.

Проблема в том, что теперь, несмотря на запуск make uninstall из исходного каталога xen, в системе, похоже, осталось много остатков xen, и я не могу найти хороший ресурс по его очистке. Я бы не возражал, если не считать, что теперь это является причиной этой проблемы (выходные данные systemctl status systemd-modules-loadи journalctl _PID=3898):

Я искал ошибочные строки загрузки модулей в /etc/modules(единственный модуль conf, ref'd by symlink from /etc/modules-load.d/modules.conf), но есть только vhost_netдля сетевого моста KVM.

Изменить: я остановил ошибки (путем удаления /usr/local/lib/modules-load.d/xen.confи перезапуска службы), но не очищен. Нашел этот список файлов, измененных во время установки, но не распознал их все.

Любые идеи о том, можно ли безопасно удалить какой-либо из них?
