Method for controlling file input and file output in a virtualized system

The invention is a file input-output occurs in, paravirtualized check the integrity of the agent, blocking the modulation of the paravirtualized agent allocated memory area to protect the paravirtualized agents, paravirtualized agent prior to running the paravirtualized agent If, by sending the file input and output information generated by host-based file system protection services, contact whether accessible, and determines the access to the generated files output by the policy engine in the host-based file system protection services, half the result of the determination hayeoseo process the file input-output occurs by transmitting to the virtualization agent to a technique for protecting a file of the file system.
