More Information
Summary:In one or more embodiments, a device may include and/or implement a physical function and multiple virtual functions that are operable to be arranged in a logical nested hierarchy and operable to be configured to respective virtual machines in a hierarchy of nested virtual machines. For example, the physical function may be configured to receive a request, issued from a virtual function of the multiple virtual functions corresponding to a Nth level of nesting of the multiple virtual functions. Until a response to the request is received, the physical function may iteratively provide the request to a virtual function of the multiple virtual functions corresponding to a current level of nesting and if the response to the request is not received from the virtual function corresponding to the current level of nesting, utilize the current level of nesting as a level immediately below the current level of nesting.
