vGPU Remapping Issue with Multiple GPUs

[bcchenbo]

Hello everyone,


My server has two GPUs: an A5000 and an A6000. Both have been successfully split into vGPU instances and appear correctly under Datacenter → Resource Mapping. I created two separate mappings for the A5000 and A6000 to make management easier.

However, when I try to add a mapping device for the A6000 to a VM, I encounter an error in VM Start Task viewer:

TASK ERROR: could not find a free device for 'hostpci0'

0001:6f:00 is A6000 PCI slot
I'd like to ask if this is due to a misconfiguration on my part, or if it's a Proxmox-related issue?


Environment:

• Proxmox version: 8.4.1
• Kernel version: 6.8.12-10
• NVIDIA driver: 570.133.10

Thanks in advance for your help!

thanks for the report, the issue is that the device is on the second pci domain '0001' which is a bit uncommon
i can see our code does not handle that correctly, and tries to prefix it with the first pci domain '0000' which leads obviously to a wrong pci id

would you mind reporting this on our bugtracker? https://bugzilla.proxmox.com
if you do, please reference this thread and post
* the vm config
* the output of `lspci`

thanks !

Of course! I've already posted this under Bug 6400 and hope it will be fixed soon!
