libvirt：错误：无法设置 AppArmor 配置文件

我正在关注这关于如何 GPU 直通的教程，但是当我到达大约 6:43 标记时，您按开始安装按钮，我收到以下错误：

Unable to complete install: 'internal error: Process exited prior to exec: libvirt:  error : unable to set AppArmor profile 'libvirt-5d739005-01d9-4c7c-9b41-bb3e3486c672' for '/usr/bin/qemu-system-x86_64': No such file or directory'

删除AppArmor配置文件似乎不起作用。

从昨天开始我一直在谷歌上搜索解决方案，但我找不到任何内容。这里有人知道为什么会出现这个错误吗？

答案1

在某种程度上似乎是一个错误，而不是你做错了什么。列出您的发行版、libvirt 和 qemu 版本可能会有所帮助。但也许可以通过禁用 apparmor 来解决这个问题/etc/libvirt/qemu.conf：

security_driver = "none"

然后重启libvirtd
