RIM Bundle Not Found on H200 Attestation

Accelerated Computing Confidential Computing
1

I am attempting to test nvattest on an H200 GPU. However, whenever I run

nvattest attest --device gpu --verifier local

as is suggested in the docs, I get back

Error 104: RIM Not Found
Backtrace:

I am unsure as to why the RIM would not be found. Doing --verifier remote against NRAS directly, I got a similar result:

In case this is still open: the driver side is fine, the VBIOS RIM is simply not published.

Checked today (3 November) against the public RIM service:

$ curl -s -o /dev/null -w '%{http_code}\n' https://rim.attestation.nvidia.com/v1/rim/NV_GPU_VBIOS_1010_0230_894_9600B70002
404
$ curl -s -o /dev/null -w '%{http_code}\n' https://rim.attestation.nvidia.com/v1/rim/NV_GPU_DRIVER_GH100_610.57.04
200
$ curl -s https://rim.attestation.nvidia.com/v1/rim/ids | jq -r '.ids[]' | grep NV_GPU_VBIOS_1010_0230_894
NV_GPU_VBIOS_1010_0230_894_9600CE000F
NV_GPU_VBIOS_1010_0230_894_9600D9000E
NV_GPU_VBIOS_1010_0230_894_9600DB0011

So for that board ID NVIDIA publishes RIMs for VBIOS 96.00.CE.00.0F, 96.00.D9.00.0E and 96.00.DB.00.11, not for 96.00.B7.00.02. Both the local verifier and NRAS need that RIM to compare the VBIOS measurements, which is why they fail the same way, and no flag on the guest side will get around it.

Two ways out: ask the server vendor (or your cloud provider) for a VBIOS update to one of the listed versions, then re-run; or, if 96.00.B7.00.02 is supposed to be a production CC VBIOS for that SKU, ask NVIDIA here to publish its RIM. After any VBIOS change, the ids endpoint is the quickest thing to check before running the full attestation.
