I can't passthrough more than 8 GPUs to same VM.
If I passthrough 9 GPUs:
If I passthrough 10 GPUs:
nothing I can see.

You are running PVE7.1 and PVE7.2 increased the allowed number ob PCIe devices via GUI from 5 to 16. Not sure when the limit was increased via CLI.

Maybe you could upgrade PVE to a supported version like 7.4 and see if that helps?

mhmm.. can you post the output of

qm showcmd <ID> --pretty
once for the variant with all gpus in the config (like you would normally configure it)
and once for the 'args' variant?
