INFORMATION TERMINAL, COMPUTER RESOURCE MANAGEMENT METHOD, AND VIRTUAL MACHINE EXECUTION SWITCHING METHOD

摘要

There is provided an on-vehicle terminal (101) having a function for surely suppressing computer resources assured by a virtual machine (1a1) or a virtual machine (1b1) within a computer resource limit value allocated to a corresponding virtual machine or a function for appropriately executing a plurality of virtual machines. When the virtual machine (1a1) or the virtual machine (1b1) requests allocation of a computer resource and if the resource is smaller than the compute resource limit value allocated to the corresponding virtual machine, the on-vehicle terminal (101) requests an OS (143) to allocate the computer resource corresponding to the request. Moreover, the on-vehicle terminal (101) checks the number of continuous selections of the previously selected virtual machine at a predetermined time interval. When the number of continuous selections is equal to the limit value or when the virtual machine is in a wait state, a different virtual machine is selected and execution of the selected virtual machine is instructed to the OS (143).
