PCIE passthrough of coprocessor not visible

[rusticsauce]

hello, I was in the process of configuring my proxmox machine which has a gpiu and a hailo AI Coprocessor module attached to it.
the host lspci command displays the Hailo Module and the GPU correctly
but when i go to create a VM the gpu passthrough is visible but not the Hailo Module.

if i create a resource mapping and attach that to a vm then the whole host crashes with it.

I am seeing the same, would love some guidance how to at least collect some additional debugging logs to help resolve the issue.

Hi folks,

I am attempting the same, while also facing this issue. So I tried to workaround it by creating Mapped PCI Device with Hailo-8L, as it is listed there, and attach it to the VM. However, the VM fails to boot. So far I have tried only one VM running Home Assistant, maybe someone else will get lucky with different config, or its just broken for everyone.
