Abstract: Disclosed is a method for protecting virtual machine data at a peripheral subsystem connected to at least one processor configured to host a plurality of virtual machines. In the method, context information, including a virtual machine identifier (VMID), is received. The VMID is unique to one of the plurality of virtual machines. A storage bank of a plurality of storage banks is selected based on the VMID included in the received context information. Each storage bank of the plurality of storage banks uses a same bus address range. A data bus is connected to the selected storage bank.
