Abstract
Embodiments of a method and apparatus for monitoring activity on a virtual machine are generally described herein. The activity may be monitored by a first hypervisor and the virtual machine may be controlled by a second hypervisor. In some embodiments, the method includes setting a breakpoint in a kernel function of the virtual machine. The method may further include generating a page fault, responsive to the virtual machine halting execution at the breakpoint, to cause the second hypervisor to page in contents of a memory location accessed by the kernel function. The method may further include inspecting the contents of the memory location to detect activity in the virtual machine.
