exactly

Hi everyone,
I am trying to get P2P communication working between two Nvidia L40s PCI GPU cards.
I did this in qemu/kvm by adding the "x-nv-gpudirect-clique=1" flag to each -device entry in the VM spec. Performance wasn't great (~13GB/s in the cuda p2pBandwidthLatencyTest), but the p2p function seems to work.
I can't achieve similar behavior in the latest xcp-ng 8.2 or 8.3 versions.

Is it possible in xcp-ng? Has anyone struggled with such a problem?

Thank you all in advance for your time and input!
