Abstract
The present invention is directed to an information handling system device for operatively coupling with a device implementing Input/Output (I/O) virtualization for data transmission. The information handling system device may be configured for executing an operating system control program to manage one or more guest operating systems on the information handling system device. The operating system control program may include a paravirtualization driver for formulating a work queue entry according to the I/O virtualization of the device. Data may be transmitted between the one or more guest operating systems and the device via the paravirtualization driver.
