Ah, right! I should have looked at the comments in PeiFvInitialization() [OvmfPkg/PlatformPei/Fv.c], from Jordan's commit b36f701d4f925. The function calls both BuildFvHob() and PeiServicesInstallFvInfoPpi(), and the comments on them explain the different purposes. One is for the DXE Core to dispatch drivers from, the other is for the PEI Core to find the DXE Core in. Thanks!
