Claim 7:
8. A method for preventing a security threat to a virtual machine, performed by an apparatus for preventing a security threat to a virtual machine, comprising:
executing, by a hypervisor for virtualization in a host kernel, a virtualization instruction corresponding to a service requested by a virtual machine of a host application; and
interrupting, by a hypervisor for monitoring, the virtualization instruction in response to a security threat event occurring in a monitoring area of the hypervisor for virtualization, and controlling, by the hypervisor for monitoring, a process and thread of the host kernel,
wherein the hypervisor for monitoring is located in an area separate from an area in which the hypervisor for virtualization is located in the host kernel,
wherein the security threat event is triggered by access to an interrupt point that is preset in the monitoring area of the hypervisor,
wherein controlling the process and the thread is configured to control the process and the thread depending on a result of a determination as to whether a memory area is an invariable area when the security threat event that causes the memory area to be altered occurs in the monitoring area.
