kvm 错误启动域：不支持的配置：无法找到模型 selinux 的安全驱动程序

Question

尝试启动我们的 kvm 虚拟机并在重新启动物理主机后出现此错误。

Error starting domain: unsupported configuration: Unable to find security driver for model selinux

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 88, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 124, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 83, in newfn
    ret = fn(self, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/domain.py", line 1479, in startup
    self._backend.create()
  File "/usr/lib/python2.7/site-packages/libvirt.py", line 1062, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: unsupported configuration: Unable to find security driver for model selinux

检入主机向我们显示 Selinux 已禁用。

$ getenforce 
Disabled

备份并运行虚拟机

我运行了以下命令来编辑域 xml 配置文件。

$ virsh edit some-virtual-machine / domain

删除虚拟机域定义 xml 启动附近的以下行。

<seclabel type='dynamic' model='selinux' relabel='yes'/>

这使虚拟机启动并运行。

您还可以在尝试启动虚拟机之前编辑 libvirt 配置目录中的配置。 /etc/libvirt/qemu/
