COMPUTING DEVICE, METHOD AND MACHINE-READABLE STORAGE MEDIA FOR SECURE INTER-VIRTUAL-MACHINE SHARED MEMORY COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide secure inter-virtual-machine shared memory communication.SOLUTION: In a computing device 100, a virtual machine monitor (VMM) 202 authenticates a view switch component 226 of a target virtual machine 204, and configures a secure memory view to access a shared memory segment 214. The shared memory segment 214 includes memory pages of a source virtual machine 206 or the VMM 202. The view switch component 226 switches to the secure memory view without generating a virtual machine exit event. The target virtual machine 204 accesses the shared memory segment 214 via the secure memory view. The target virtual machine 204 and the source virtual machine 206 may coordinate ownership of memory pages using a secure view control structure stored in the shared memory segment 214.SELECTED DRAWING: Figure 2
