KVM + Xenial 服务器。libvirt-bin 不会配置

Question

我只是（愚蠢地）完成了从 14.04.4 到 16.04 的升级。显然，由于引入 systemd 会破坏 libvirt ……或者我破坏了 aptitude。是否有解决方法或修复方法？我应该回到 14.04 吗？

这似乎是由 apparmor 引起的，因为您会在系统日志中找到与此类似的内容：

内核：[2386.130467] 审计：类型=1400 审计（1461767119.644:89）：apparmor="DENIED" operation="create" profile="/usr/sbin/libvirtd" pid=21368 comm="libvirtd" family="netlink" sock_type="raw" protocol=0 requests_mask="创建" denied_mask="创建"

在修复错误之前，一种不安全的解决方法是暂时禁用安装的 apparmor：

sudo systemctl stop apparmor.service
sudo apt-get -f install
sudo systemctl start apparmor.service
