10 months ago There's a script lxc/hooks/nvidia which executes using the device name. However the device name is provided by something else before that script starts. Is this the source of the device name?
Notice we don't use the gpu.Nvidia.UUID at all anymore. Instead we need to use the MIG UUID, which is a completely different UUID. Note the difference:
# nvidia-smi -L
GPU 0: NVIDIA A100 80GB PCIe (UUID: GPU-932bfb2c-849a-2a22-1e84-9eff6bc02b39)
MIG 3g.40gb Device 0: (UUID: MIG-0929581a-2be6-5dec-bf34-0954c6c529a6)
MIG 3g.40gb Device 1: (UUID: MIG-3adbed3a-d03d-549f-a016-ba1fd7359f23)

10 months ago @simondeziel do any of the testflinger machines have MIG cards? is this something you could take a look at?

10 months ago @greenmoss IIRC, our MIG tests all passed on a system with 2x NVIDIA-A100 cards. Our test environment differs a bit from yours though:
I'll rerun the tests and see if I can reproduce your issue.

10 months ago @greenmoss I can reproduce your issue when using mig.gi and mig.ci:
# lxc config device add nvidia-mig1 gpu0 gpu gputype=mig mig.ci=0 mig.gi=5 pci=0000:21:00.0
# lxc config show nvidia-mig1
