Abstract:
A method includes determining a reference I/O service time of an I/O operation on a server and measuring, with a processor of the server running a hypervisor configured to manage a plurality of logical partitions (LPARs), each LPAR running one of a plurality of instances of an operating system (O/S), an actual I/O service time of the I/O operation. The method also includes determining, by the processor, a delay time of virtualization on the server based on the reference I/O service time and the actual I/O service time.
