So we have a specific use case: COMPUTE_TRUSTED_CERTS + NUMA requires placement to support traits on RPs that are not providing resources. Will in this case VCPU and MEMORY_MB always requested in the unnumbered group still? Or there are cases when those resources are requested in a numbered group?
That'll depend on the outcome of the various NUMA modeling discussions; but as soon as we need to be able to request resources from more than one NUMA node, it seems certain that we'll need to use numbered groups.
Then we need two steps: 1) handle RPs that only have traits but not resources 2) allow having the numbered request groups specify only a trait without requesting resources. Cheers, gibi
