KVM + Xenial 服务器。libvirt-bin 无法配置

KVM + Xenial 服务器。libvirt-bin 无法配置

我刚刚（愚蠢地）完成了从 14.04.4 到 16.04 的升级。显然，由于引入了 systemd，导致 libvirt 出现错误……或者我破坏了 aptitude。有解决方法或修复方法吗？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发现类似这样的内容：

内核：[2386.130467] 审核：类型 = 1400 审核（1461767119.644：89）：apparmor =“DENIED”操作 =“创建”配置文件 =“/usr/sbin/libvirtd”pid = 21368 comm =“libvirtd”family =“netlink”sock_type =“raw”协议 = 0 requested_mask =“创建”denied_mask =“创建”

在该错误修复之前，一个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

请不要取消注释此内容/etc/libvirt/libvirtd.conf：

# You need to uncomment this line
log_outputs="3:syslog:libvirtd"

保留默认设置，例如：

# You need to uncomment this line
#log_outputs="3:syslog:libvirtd"

在官方 libvirt wiki 中提到了这一点：http://wiki.libvirt.org/page/The_daemon_cannot_be_started，但这根本没有帮助。

最好的选择是首先运行：

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

然后你可以尝试：

systemctl status libvirt-bin.service

其输出应如下所示：

libvirt-bin.service - Virtualization daemon

我在使用 apt dist-upgrade 时也遇到了类似的问题。我通过停止 libvirt-bin 服务并终止所有正在运行的 libvirt 进程来修复此问题。
