1. In a computing environment, a method comprising: determining a current computing environment; creating low-level interfaces based on the current computing environment; and wherein the current computing environment corresponds to processor information, and wherein dynamically creating the low-level interfaces comprises constructing a dispatcher by patching over host mode interrupt code in the interrupt vector space based on the processor information and writing the dispatcher into interrupt vector space, the dispatcher configured to branch from the interrupt vector space to a guest-mode interrupt vector at interrupt time.
