[求助/Help]海光DCU K100-AI 设备透传问题，虚拟机启动失败

[aa644728538]

已经配置了自定义设备透传，并且能识别

启动虚拟机时报错

[wanyaoqi]

上宿主机看下 cat /opt/cloud/workspace/servers/ID/desc | jq .isolated_deviecs

ID 替换成虚拟机 id

[aa644728538]

我用你的命令，结果是null的
我直接jq . desc是有的

[wanyaoqi]

应该是 cat /opt/cloud/workspace/servers/ID/desc | jq .isolated_devices ，上面打错字了

[wanyaoqi]

lspci 看下这个设备有多个 function呢 lspci | grep '1d:00'

[aa644728538]

[wanyaoqi]

需要查一下这个设备的 iommu group 中有多少个设备 https://chat.deepseek.com/share/6347mgiem9ynl39is6
