Abstract
A method, apparatus, and computer-readable storage medium for managing operations within virtual machines are provided. According to one embodiment, a virtual machine manager monitors the internal operations of the virtual machines by redirecting a reference from a first address to a second address. The first address is an address of a function to be executed by the virtual machine. The second address is an address of a memory location in the memory page. The virtual machine manager installs an execution event at the memory location. In response to a request resulting in the memory location being accessed, an execution event is triggered. In response to the triggering of the execution event, a message is sent to the hypervisor. The message indicates that the memory location has been accessed.
