Virtual machine monitor to i/o stack conduit in virtual real memory

An apparatus for handling a request from a virtual machine monitor in a computing system, comprising:

• a processor;
• a computer-readable storage medium;
• a virtual machine monitor;
• a virtual interface;
• an operation-specific module;
• and
• instructions, stored on the computer-readable storage medium and executed on the processor, for performing a method, the method comprising:
• receiving, at the virtual interface from the virtual machine monitor, a request directed to a service provider device;
• converting the request to a format common to a plurality of two or more different types of operation-specific modules to produce a formatted request;
• transmitting the formatted request to an operation-specific module of the plurality of operation-specific modules;
• converting, by the operation-specific module, the formatted request to a command format corresponding to the service provider device;
• transmitting, by the operation-specific module, the service provider device formatted request to the service provider device;
• receiving a response from the service provider device at the operation-specific module;
• converting, by the operation-specific module, the response from the service provider device to the format common to the plurality of two or more different types of operation-specific modules to produce a formatted response;
• transmitting, by the operation-specific module, the formatted response to the virtual interface;
• converting the formatted response to a format corresponding to the virtual machine monitor;
• and
• transmitting the virtual machine monitor formatted response to the virtual machine monitor.
