unraid 6.12 RC3

[kingjoydom]

重启之后报错

VM Autostart disabled due to vfio-bind error

[zhtengw]

您好，有没有在tools->system device里面把设备绑定到vfio-pci，要去那里绑定了才能每次启动都生效。

[kingjoydom]

我时在这边绑定了重启后报的错

[zhtengw]

那查一查日志，看看提示的vfio-bind错误是哪些设备导致的

vfio-pci binding complete

看这个日志，好像没有啥错误

[kingjoydom]

Issue is VFIO check is completed before plugin is loaded so 2.1 and 2.2 don't exist. You don't need to bind them to VFIO.

看起来没问题，手动启动VM应该是正常的，可能是6.12.0-rc3里加载插件和启动VM的顺序变了，在加载插件之前先尝试启动VM，所以找不到绑定的设备了。我升级个rc3试一下，看看有没有办法。

他是Unraid认证的社区开发者，跟我想的差不多。

我换了个方式，虚拟出来的显卡不绑定直通，直接在VM里面用就好了。

对，也可以，启动虚拟机的时候会自动把直通的pci设备用vfio-pci去驱动，而虚拟的vf显卡主机用不上的，直接虚拟机里用就行。

哇 cool 我这两天也因此困扰，导致我openwrt 都不能在重启后自启动。都不绑定后啥问题都没了 该调用还是调用 舒服了～
