What is the bottle neck of Virtualization today?

What does IOPS means? IOPS (Input/Output Operations Per Second, SCALE AND PERFORMANCE pronounced eye-ops) is a common performance measurement used to benchmark computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). The most common performance characteristics measured are sequential and random operations. Sequential operations access locations on the storage device in a contiguous manner and are generally associated with large data transfer sizes, e.g., 128 KB. Random operations access locations on the storage device in a noncontiguous manner and are generally associated with small data transfer sizes, e.g., 4 KB Source:
