Abstract
A method and system to map virtual I/O devices and resources to a standard I/O bus is provided. The system, in one example embodiment, comprises a virtual device detector, a resource allocator, and an activation module. The virtual device detector may be configured to detect an indication of a virtual Peripheral Component Interconnect Express (PCIe) device having an associated template. The resource allocator may allocate, based on the template, a plurality of resources required for the virtual PCIe device from a pool of available resources. The activation module may generate a set of entries in a resource mapping table, the set of entries corresponding to the allocated resources and defining the virtual PCIe device.
