Claim 0:
1. A data processing device comprising:
a central processing unit (CPU) that executes i) each of a plurality of virtual machines and ii) a virtual machine manager that manages the plurality of virtual machines;
an interrupt information storage that stores data for channels, and outputs an interrupt request with data corresponding to one of the channels when a signal is received from the one of the channels;
an interrupt controller that receives, from the interrupt information storage, the interrupt request with the data that specifies at least one of the virtual machines and the virtual machine manager; and
a counter that counts, based on the data, i) the number of the interrupt request executed in each virtual machine and ii) the number of the interrupt request executed in the virtual machine manager,
wherein the interrupt request to be counted by the counter is an interrupt request output with the data set in count target setting information.
