Virtualization system and operation management method

A virtualization system in a network compatible vehicle-mounted system, the virtualization system running a plurality of guest operating systems in a virtual environment, the virtualization system comprising:

• a hypervisor that i) controls operations of the plurality of guest operating systems in the virtual environment and ii) manages parameters for generating allocation information indicating allocation of hardware resources of the virtualization system to the guest operating systems;
• and
• a resource identifier that manages access to the hardware resources based on the allocation information,
• wherein the hypervisor transmits the parameters to the guest operating systems and the resource identifier,
• wherein the respective guest operating system generates an updated operating system identifier when a preset update timing interval has passed, and requests the resource identifier to access the hardware resources based on the operating system identifier,
• wherein the resource identifier compares the updated guest operating system identifier with an operating system identifier stored in a register,
• wherein the register stores an operating system identifier that is granted permission for access to the resource, and
• wherein the resource identifier permits access if the updated guest operating system identifier matches the operating system identifier stored in the register.
