PCKIDRetrievalTool (Unexpected error occured while sending data to cache server)

RayWang1 — Fri, 23 Feb 2024 00:02:13 GMT

Follow all of the TDX/SGX guide to install PCCS server on the host, subscribe to the Product Intel® Software Guard Extensions Provisioning Certification Service , have the primary/secondly key, and lunch the PCKIDRetrievalTool , and return errors.

[root@localhost sgx-pck-id-retrieval-tool]# ./PCKIDRetrievalTool

Intel(R) Software Guard Extensions PCK Cert ID Retrieval Tool Version 1.20.100.2

Warning: platform manifest is not available or current platform is not multi-package platform.

Please input the pccs password, and use "Enter key" to end

maybe you didn't do registration. Would you please paste your PCKIDRetrieval tool's output file's size?

This error is important: "Warning: platform manifest is not available or current platform is not multi-package platform."

At this point, probably best to "Enable" the "SGX Factory Reset" in the BIOS. This will force a new Platform Manifest to be created which is required for platform registration, which is required to download a platform PCK Cert. This is only for Xeon Scalable CPUs, though, like 3rd, 4th, or 5th Gen Xeon Scalable CPUs. Xeon E's do not require this.

Also note, this only works in the host OS/on bare metal. You cannot get to the platform manifest if running inside a VM.

We did enable the SGX and also try the SGX Factory reset multiple times, it does not help. and from our mpa_registration log, it already shown pass.

(...) Also note, this only works in the host OS/on bare metal. You cannot get to the platform manifest if running inside a VM.

@Scott_R_Intel @RayWang1 Does this mean there is no way to run the PCCS service inside a Docker container? Must the PCCS service be running directly in a non-virtualized environment? If that's the case, is this requirement documented in the SGX manuals? Where can I find it?

I'm asking because I'm trying to get PCCS working with Docker, but keep hitting the same issue mentioned before:

Warning: platform manifest is not available or current platform is not multi-package platform.

and:

Error: No cache data for this platform.

I'm not sure if that is because of some fundamental reason of how PCCS/SGX works, or if I just set something up wrong.
