Virtual device composition in a scalable input/output (I/O) virtualization (S-IOV) architecture

At least one non-transitory computer-readable medium comprising instructions stored thereon, that if executed by one or more processors, cause the one or more processors to:

• execute an operating system (OS) compliant with Scalable Input/Output (I/O) Virtualization (S-IOV) to execute a Virtual Device Composition Module (VDCM) to:
• utilize a virtual device (VDEV) to transmit data to resources of a shared physical device and receive data from the resources by accessing an Assignable Device Interface (ADI) and
• assign the virtual device to a virtual machine, the virtual machine to access the resources of the shared physical device by accessing the ADI, wherein
• the OS comprises the VDCM,
• the one or more processors execute the VDCM, and
• based on the shared physical device comprising a network controller device, the ADI is associated with receive and transmit queues to store packets.

An apparatus comprising:

• a device comprising resources accessible by a virtual machine as a Scalable Input/Output (I/O) Virtualization (S-IOV) compatible virtual device (VDEV) and by an Assignable Device Interface (ADI), wherein:
• a processor-executed operating system (OS) comprises a Virtual Device Composition Module (VDCM),
• the processor executes the VDCM, and
• based on the device comprising a network controller device, the ADI is associated with receive and transmit queues to store packets.
