System and method for logging operations of virtual machines

A computer system comprising:

• at least one processor;
• a computer-readable storage medium coupled to the at least one processor;
• and
• computer code, encoded in the computer-readable storage medium, configured to cause the at least one processor to
• redirect a reference from a first address to a second address, wherein
• the reference initially refers to the first address,
• the first address is an address of a function to be executed by a virtual machine, and
• the second address is an address of a second memory location in a memory page within the virtual machine,
• install an execution event at the second memory location,
• trigger the execution event, in response to a request to load a software module in the virtual machine, wherein
• the execution event, when triggered, is configured to cause an indication to be sent to a hypervisor,
• send the indication to the hypervisor that the software module is loaded in the virtual machine, in response to the triggering of the execution event,
• access a first memory location in the virtual machine, in response to the indication, wherein
• the accessing is performed using the hypervisor,
• a value is stored in the first memory location, and
• the value identifies the software module, and
• return the value to the hypervisor.

A non-transitory computer-readable storage medium comprising computer code, when executed, the computer code is configured to cause a processor to:

• redirect a reference from a first address to a second address, wherein
• the reference initially refers to the first address,
• the first address is an address of a function to be executed by a virtual machine, and
• the second address is an address of a second memory location in a memory page within the virtual machine;
• install an execution event at the second memory location;
• trigger an execution event, in response to a request to load a software module in the virtual machine, wherein
• the execution event, when triggered, is configured to cause an indication to be sent to a hypervisor;
• send the indication to the hypervisor that the software module is loaded in the virtual machine, in response to the triggering of the execution event;
• access a first memory location in the virtual machine, in response to the sending wherein
• the accessing is performed using the hypervisor,
• a value is stored in the first memory location, and
• the value identifies the software module;
• and
• return the value to the hypervisor.
