[讨论/分享] 分享一个ubuntu虚拟918+开启photo人脸识别的办法

本帖最后由 ma20at 于 2021-10-7 02:08 编辑

之前的虚拟机类似是用uefi模式创建的，显卡启用gvt-g后jellyfin可以识别vGpu开启硬解，photo的人脸无法识别。今晚没事干看到有个网友分享了pve开启人脸识别，就重新创建了一个bios模式启动的虚拟机，终于可以识别了，我有多个虚拟机所以需要gvt-g虚拟多个vGpu，单虚拟机直接显卡passthrough也一样。ubuntu宿主机怎么启用gvt-g就不说了官方有文档可以参考。大概步骤:1. 虚拟机类型选择i440fx芯片组BIOS启动，os选择redhat6. vCPU选择kvm64就行，网卡类型直接virtio可以识别。

2.虚拟机虚拟gpu设置部分，我懒得截图，直接把虚拟机的配置文件贴出来，直接参考最后<graphics type="spice">到结束部分。

3.上图看看效果。
