Abstract
A system and method for locating a memory page in a guest virtual machine are provided. An execution event is triggered, in response to a request to allocate a first memory page in a virtual machine. A processor sends an indication to a hypervisor that the first memory page has been allocated in the virtual machine, in response to the triggering of the execution event. Responsive to receiving the indication, a security virtual machine appropriates control, via the hypervisor, of the first memory page allocated in the virtual machine and inserts program code in the first memory page. The processor executes the program code. The security virtual machine relinquishes control of the first memory page allocated in the virtual machine, in response to determining the program code has completed execution.
