Method and apparatus for supporting universal serial bus devices in a virtualized environment

摘要

A method for managing data between a virtual machine a bus controller includes transmitting an input output (IO) request from the virtual machine to a service virtual machine that owns the bus controller. According to an alternate embodiment, managing data between a virtual machine and a bus controller includes trapping a register access made by the virtual machine. A schedule is generated to be implemented by the bus controller. Status is returned to the virtual machine via a virtual host controller. Other embodiments are described and claimed.
