VIRTUAL MACHINE SYSTEM AND METHOD OF MEASURING PROCESSOR PERFORMANCE |
| 摘要 |
In a virtual machine system where a first stage VM and a second stage VM generated on the first stage VM are executed, a processor is configured to perform a first determination as to whether to physically instruct to start execution caused by a virtual execution start of the second stage VM and a second determination as to whether a physical end is detected as a result of a virtual end of the second stage VM, and calculate an execution time of the second stage VM based on results of the first determination and the second determination. |

1. A virtual machine system, comprising:
a memory; and a processor configured to execute a first stage VM (Virtual Machine) and a second stage VM generated on the first stage VM, the processor being coupled to the memory, wherein the processor is configured to
perform a first determination as to whether to physically instruct to start execution caused by a virtual execution start of the second stage VM and a second determination as to whether a physical end is detected as a result of a virtual end of the second stage VM, andcalculate an execution time of the second stage VM based on results of the first determination and the second determination. |
