Patent ID: 11520906

Abstract:
A computer-readable medium comprises instructions that, when executed, cause a processor to execute an untrusted workload manager to manage execution of at least one guest workload. The instructions, when executed, also cause the processor to (i) receive a request from a guest workload managed by the untrusted workload manager to access a memory using a requested guest address; (ii) obtain, from the untrusted workload manager, a translated workload manager-provided hardware physical address to correspond to the requested guest address; (iii) determine whether a stored mapping exists for the translated workload manager-provided hardware physical address; (iv) in response to finding the stored mapping, determine whether a stored expected guest address from the stored mapping matches the requested guest address; and (v) if the stored expected guest address from the stored mapping matches the requested guest address, enable the guest workload to access contents of the translated workload-manager provided hardware physical address.
