interface BoxCreateParamsCPUMillicores optionally requests CPU at millicore granularity (e.g. 500 = 0.5 vCPU); takes precedence over VCPUs. Fractional (sub-vCPU) values are not available for every sandbox.
RestoreMemory selects how the sandbox handles a snapshot's captured memory:
nil → if-present: resume from memory when the snapshot has it, else cold-boot (default). true → always: resume from memory; rejected if the snapshot has none. false → never: always cold-boot.
Applies to this request only.
