畅网N100 先锋版 V2 PVE安装飞牛核显直通一直失败，求助

畅网N100先锋版的主机，PVE搞ALL IN ONE，最近安装好飞牛之后想搞核显虚拟化之后直通。之前用的是PVE的8.1.1版本，做过核显直通，给Openwrt挂Docker之后用Alist调用，那时候一直没有成功过。这次反复实验了很多PVE的内核版本，最后还是没有能成功。总是在飞牛影视里设置GPU加速的时候，选择GPU的时候出现一个“0”，在飞牛的CPU/GPU监视的弹窗里。GPU也显示是“-”。说明飞牛根本就没有加载好GPU，而且在飞牛启动的时候，会提示I915驱动失败的提示。

后来发下，只要不开SRIOV就ok，打开SRIOV后，能看到分出来的虚拟核显，但是一旦选择虚拟核显，飞牛就会报错。进去之后GPU显示不出来。如果将其中1个虚拟核显分配给其他虚拟机，飞牛就根本无法启动了，直接启动就报错。（感觉就是飞牛一定要整个核显不论是主核显，还是分裂出来的虚拟核显，都不能有其他虚拟机占用，否则启动不了）

但是飞牛虚拟机一旦直通主核显，那么就没问题，说明其实显卡直通是ok的，就是SRIOV的虚拟核显有问题。

以下是SRIOV的核显飞牛时的报错信息：

以下是用主核显启动飞牛，就没有报错

我查了一下似乎是bios的问题?还是pve的驱动的问题？
