Hello, I am using Proxmox hypervisor and I'm trying to get CP1623 to passthrough to a virtual machine. This far I've got it to register in device manager in the VM and in adapter settings i also see it, but it fails to startup in Station Configurator with error 0x0381, the exact message is as follows:

No     Time stamp          Subsystem Event
216 !! 27/06/2024 10:44:47 Router    The CP with index 3 is not operational

Details:
The CP with index 3 is not operational!
Error 0x0381  occured.

 Cant seem to find much information on it, this is for virtualisation of PCS 7 system, 2 redundant servers 1 ES, this is only for virtualisation test so far so i can do whatever.

I have 3 CP1623 in the host machine, 1 for each. i attached my PCI connected devices as file "pvesh get.txt"

At the start I was not really sure which device to passthrough as theres 2 devices linked in slot x (19-22) but after fiddling a bit i found that the ones named "MPC8347 PBGA" are the ones i wanted to passthrough, but I'm not 100% sure this is correct setup, does anyone have any experience with this? For example further information on error 0x0381 I cant find much, or PCI passthrough of CP1623

Further information:
My conversion to virtual machine was using vmware vcenter converter and using file format vmdk still on the virtual machine in proxmox, no error leds on physical cp card or anything
