Abstract
A non-volatile memory (NVM) express (NVMe) system includes at least one user application, an NVMe controller and a hypervisor. Each user application runs in a respective virtual machine environment and including a user input/output (I/O) queue. The NVMe controller is coupled to at least one NVM storage device, and the NVMe controller includes a driver that includes at least one device queue. The hypervisor is coupled to the user I/O queue of each user application and to the NVMe controller, and selectively forces each user I/O queue to empty to a corresponding device queue in the driver of the NVMe controller or enables a private I/O channel between the user I/O queue and a corresponding device queue in the driver of the NVMe controller.
