A data processing system facilitates virtual machine migration with direct physical access control. The illustrative data processing system comprises a software-programmable trap control associated with hardware registers of a computer that selectively vectors execution control of a virtual machine (VM) between a host and a guest. The data processing system further comprises a logic which is configured for execution on the computer that programs the trap control to enable the virtual machine to directly access the hardware registers when the virtual machine is not migrated and to revoke direct access of the hardware registers in preparation for virtual machine migration.

Systems, methods, and other embodiments associated with automatically detecting and characterizing a power topology are described. One example system includes a topology logic that identifies connections between PDUs and computers that receive power from the PDUs. The example system may include a data store that receives PDU/computer association data from the topology logic. A computer may communicate with a power providing PDU over a power line connecting the two devices. The computer and the power providing PDU may be configured with network interface devices (e.g., Ethernet switches) configured to communicate over the power line using, for example, EoP. The topology logic may discover a PDU/CE association by examining data transmitted over a network to which the computer and/or the PDU are connected.

One or more workloads are simulated on a resource, where each of the one or more workloads represents at least one application configured to run on the resource. A required capacity of the one or more workloads is determined based on the simulation.
